Most the people I followed on here when there was the big "dump Tumblr and Twitter, go to NG" exodus haven't posted in like 2-3 years. Pillowfort is also basically a ghost town. For all the shit people talk about Twitter they're still keen on using it.

For all it worth. I don't like this site either. Too many obsolete legacy features and the ultra toxic southpark-esque background from all the older users.
But it's precisely because the way twitter is designed to work that people both hate it and are terminally addicted to it.

I do like Newgrounds since it's gotten me to interact more and try community events. Don't like the circlejerking it tends to do, like with the front page background you mentioned. I'm more mocking everyone who was all gung-ho about "time to dump Twitter" only to just go back to it and not even bother with the alternatives.
