Hopefully this won't turn into a total Andy Rooney Rap session, but it'd be good to get some of those little(or big) things that bug us about social networks and how people act on them out in the open and possibly avoid such issues here. So out with it, what are those beefs? P.S. I'd start this off, but instead I will now have mercy upon you all and shut up!
