Here's a traffic graph of the growth of amount of subreddits over time.

Oh mehn, this is a crazy growth here

Here on Steem we've gotten used to #life being on top constantly for some weird reason, I personally find it to be a pretty dumb tag to use in your post

U know I also have same feeling when making use of the #life tag but somehow it feels like most ofy posts have to do with life itself and so I just make us of it. Many people have called it a useless tag Coz they don't get curated and I think it's because, just like you said, everyone is using the tag so ur posts gets buried

Talking about communities on Steemit, I haven't been around lately to monitor what's been going on around here but I think that communities like #steemjet, #steemiteducation, #steemstem and the like will really do well around here .
