I know this will be ironic as I'm posting...but I'm trying to post less on HN/FB/Reddit. I find myself spending time replying, checking karma or upvotes etc...I get emotionally attached if people like it, or dislike it. I can spend 5 minutes reading an article and multiples of that following up...It becomes a diminishing point of return.

If I do post on Reddit I'll disable inbox replies and just check once a day or something for any replies.

Edit: Also since HN doesn't have a 'disable inbox' type (that I know of?), 75% of the time I'm not logged in. I'll log in if I really have a comment and then log back out.
