I used to think that, the more followers a blog has, the more popular its posts will be. It only stands to reason, right? I also had this idea that artists have a lot of influence on Tumblr partially because of how the platform privileges images but mainly because of their relatively high follower counts.
I’ve since figured out that what’s actually going on is that a post needs to be “vetted” in order to spread. In other words, a post needs to be reblogged by someone whose taste other people trust. Or, well, “taste” is a strong word, as is “trust.” What I mean is that people are far more likely to reblog a post if someone they’re following reblogs it, even if they’ve already seen it posted on the original blog. If that “someone else” is associated with the same fandom as the post, then it will spread farther. In this case, “fandom” can be very broad; like, say, the “intellectual shitpost” fandom.
At this point I have far more followers than my small blog on Tumblr deserves, but it’s not my follower count alone that enables any given one of my posts to spread. By itself, one of my fandom-related posts might get forty to ninety notes, and it’s only when someone associated with the fandom reblogs it that it will get more than a hundred.
I’ve seen this happen on posts I’ve reblogged as well. Sometimes I’ll reblog something from a few months (or even years) ago, and it will go from having about twenty to thirty notes to having several hundred almost overnight.
Once a post reaches a certain level of critical mass, the number of notes alone will indicate that it’s already been vetted, and it will also be picked up by the site’s promotional algorithms. Before it can go viral, however, a post first needs to have community support.
I feel like the same applies to Twitter – albeit to a lesser extent, as Twitter’s septic open wound of an algorithm aggressively prioritizes a handful of tweets while hiding most of the rest, even if you turn off the “best tweets first” feature. As far as I can tell, Twitter doesn’t have the same “recommended for you” algorithm that Tumblr has, in which the posts liked by your mutuals – and the posts posted by people followed by your mutuals – will sometimes appear at the top of your feed. Rather, Twitter has figured out what types of tweets are most likely to provoke a reaction (generally negative) from you and show those tweets to you over and over until you either like them, hide them, or blacklist whatever keyword or hashtag they’re using.
Regardless, I’ve noticed that there’s still something of an influencer culture on Twitter, whereby people are more likely to respond to or retweet something if it’s already been vetted by someone they trust, even if they already follow the OP.
Meanwhile, Instagram is testing a feature that will hide the number of likes a post has received specifically for the purpose of protecting the mental health of their users, and I for one could not be more relieved.
