I mostly dialled out of Twitter as well - I'll still check some accounts occasionally, but I gave up on the timeline. I'd be excited to try a Twitter without bot amplification and (perhaps?!) some poster accountability.
I still enjoy Instagram. It's easy to tailor that to things I want to see - cats, watches, denim - and I can avoid the comments. I'd hate to been a teen with instagram though. I can imagine you could end up feeling very inadequate pretty quickly.
Man, the Internet is a funny thing. On one hand it's so great. On the other- what a disaster. I guess it's like everything, you gotta find the balance that works for you and just keep an eye that it stays balanced.
