I pledge to give $75 to MIRI if I make any more posts on this account or on my reddit account before the date of October 13 (two months from now).

Quick, everyone! If we can do it for less than $75, then let's make LW super extra interesting to gothgirl420666 for the next two months. :D

Joking aside, perhaps an effective strategy for making yourself spend less time online is to reduce your involvement with online communities -- for me at least, flashing inbox icons and commitments made to people on various forums (such as promising you'll upload a certain file) are a big part of what makes me keep coming back to certain places I want to spent less time at. If it weren't for that nagging feeling in the back of my mind, that I'll lose social cred in some place if I don't come back and act on my promises, or vanish for a few months and leave PMs unanswered, I'd be tempted to make a "vow of online silence" too.
