Friends: How many is too many?

Original image

Okay, I'll admit it: I don't have time to read more than half the tweets and status updates sent out by my friends on Facebook and the people I'm following on Twitter. And I only have 200 on Twitter and 350 on Facebook. In fact, on most days, I probably only read one third of the chatter (and I don't mean that in a pejorative way). There have been a few pieces floating around the Web lately that say the average person can only keep track of about 100-300 people maximum; after that, it just becomes white noise. (And did you know Facebook limits you to 5,000 friends?) And it also works against the very idea of social media: that you're creating a community to "interact with," (that's the 2.0 model) not amassing thousands to "speak at" (the 1.0 model).

So what about all these friends of mine who have 1,000 Facebook friends or 2,000! What about my Twitter followers who are following that much, or even say 25,000 people? Clearly most of the followers/friends have been "hidden" or banished to a far away tweetdeck column that they don't read, right? Because it would be impossible to read any significant amount of such volume. So if that's the case, here's the question: Why have 2,000 friends on Facebook? Why follow 25,000 people on Twitter?

One theory: it's impolite not to Friend or Follow someone who has initiated the same. Or how about this theory: it's all about the numbers--the more you have, the more popular you are - and who doesn't like to be popular?

What's your take? How many friends or followers do you have and how many is too many? We'd love to know how you handle the issue and what you think about all the white noise.

5 Quick Facts About the Hashtag

The use of the hashtag as a Twitter tool to denote a specific topic in order for the masses to follow along turns 10 years old today, having first been suggested (in a Tweet, naturally) by Silicon Valley regular and early adopter Chris Messina back in 2007. Here’s a little history on its evolution from the humble numerical sign to the social media giant it is today.

1. IT COMES FROM THE LATIN TERM FOR “POUND WEIGHT.”

There’s no definitive origin story for the hash (or pound) symbol, but one belief is that when 14th-century Latin began to abbreviate the term for pound weight—libra pondo—to “lb,” a horizontal slash was added to denote the letters were connected. (The bar was called a tittle.) As people began to write more quickly, the letters and the tittle became amalgamated, eventually morphing into the symbol we see today.

2. IT SHOULD ACTUALLY BE CALLED AN OCTOTHORPETAG.

The symbol portion of the hashtag eventually made its way to dial-button telephones, the result of AT&T looking forward to phones interacting with computers. In order to complete a square keypad with 10 digits (including 0), they added the numerical sign and an asterisk. AT&T employee Don MacPherson thought the sign needed a more official name, so he chose Octothorpe—“octo” because it has eight points, and “thorpe” because he was a fan of football hero Jim Thorpe.

3. TWITTER WASN’T BIG ON THE IDEA AT FIRST.

When web marketer Messina had the notion to add hashtags to keep track of conversations, he stopped by Twitter’s offices to make an informal pitch. He came at a bad time: Co-founder Biz Stone was trying to get the software back online after a crash and dismissed the idea with a “Sure, we’ll get right on that” burn. Undeterred, Messina started using them and the habit caught on.

4. IT’S IN THE OXFORD DICTIONARY.

By 2014, respect for the hashtag had grown to the point where the venerable Oxford English Dictionary gave the word its stamp of approval. Their entry: "hashtag n. (on social media web sites and applications) a word or phrase preceded by a hash and used to identify messages relating to a specific topic; (also) the hash symbol itself, when used in this way."

5. THERE ARE SOME HASHTAG ALL-TIMERS.

Hashtags can highlight interest in everything from political movements to breaking news stories, but the frequency of their use is often tied into popular culture. The most popular TV-related tag has been #TheWalkingDead; #StarWars sees a lot of action; and #NFL dominates sports-related Tweets.

How You Instagram Can Reveal Whether or Not You’re Depressed, Study Says

How you Instagram might reveal more about you than just what you did last weekend. One study found that certain Instagram photos can predict the markers of depression, as New York Magazine's Select All reports. And it's not the first study to link social media use and mental illness.

The study, in EPJ Data Science, looked at almost 44,000 posts from 166 people (71 of them depressed) using color analysis, metadata, and face detection software. (While less than 200 people isn’t a big enough number to really cement these findings, they at least analyzed a whole lot of brunch pics.) They found machine learning could successfully distinguish between the behavior of people diagnosed with depression and those with a clean bill of mental health by looking at the Instagram filter type of photos, the setting, whether or not there were people, color, brightness, and how many “likes” and comments it got. They also looked at how often people used the app and how often they posted.

The researchers’ Instagram model worked the majority of the time to correctly identify depression, even in posts made before the researchers diagnosed the person’s mental health status. Compare that to general practitioners' rates for correctly diagnosing depressed patients, which studies have found hover around 42 percent.

Depressed people tended to post darker photos, often using Instagram’s black-and-white Inkwell filter. They received more comments, but fewer likes on their posts. They tended to post photos of faces, but typically fewer faces than non-depressed users (social isolation is often linked to depression). By contrast, healthy people loved Valencia, which lightens images, and tended to get more likes.

Loving a black-and-white photo doesn't necessarily mean you're depressed. Maybe you’re just trying out your best Ansel Adams impression. But given the outsized role social media plays in modern life, it might be able to provide doctors with insights into patients' inner thoughts and feelings that they might not otherwise be privy to.

Other studies, too, have found that technology use can provide a window into people's souls, mental health and all. Research has found that unhappy people use their smartphones to cope with negative feelings, linking increased phone usage to anxiety and depression. A 2015 study found that smartphones could predict depression by tracking how often and where people moved.

In some cases, though, social media seems to play an active role in making people unhappy, rather than simply revealing their existing unhappiness. A 2017 study of 5000 people found that the more time people spent using Facebook, the worse their sense of well-being. (And that's even before you start talking about reading the news.) Other surveys have found that for teenagers, Instagram and Snapchat usage are associated with low self-esteem, bullying, and more.

But even if obsessively Instagram is making you unhappy in the first place, how you use social media could be an important factor for doctors to consider when evaluating mental health. It's hard to open up to people about depressive thoughts, especially if it's a medical professional you only see once a year. You might tell your doctor you feel fine, but be more honest about your inner darkness on Instagram—whether you realize it or not. So although you probably don’t want to hand over your social media history to your medical providers on a regular basis, it could provide a useful way to screen patients who aren't able to fully convey their mental health issues.
