Reply to all comments that is made on your posts
I always say at least thank you even if comment is just thumbs up emoji or a few words like ,,nice post''. In the past I used to even upvote every comment I got. Only recently I became more selective about what I upvote.
Yeah I've recently started getting a little more selective as well. I enjoy the small comments more than nothing at all, but definitely like when people take the time to provide a thoughtful comment (shows they actually read at least part of the content!).
