Facebook owns my life
This may seem completely random, but looking back at the amount of time I've spent on Serendip, both reading other people's posts and blogging myself, I really wish there was some version of a "like" button on posts. Sure, maybe that's an indication that I spend far too much time on Facebook, and it could cut down on comments. But for the rest of us who want to acknowledge what a user has to say, but don't want to repeat what other commenters have written, have a "like"button would be a really useful tool. Also, the poster themselves could get much more feedback, because they know that what they wrote is actually being read.
Maybe something to think about in the future?
