No thanks. You'd get a well informed and educated post from Guppy about Spit12s go with 1 thank, but the "QUAHOMGWTFBBQNONUKES!!!!11!!11eleven!!!" get 20,000 "likes" .....
Hell, too many folks with shades as-is. They'd create shades to give themselves "likes" on the forum, thinking it actually means something.
Look at all the post-padding currently. Hell I recall one guy got banned from the forums some years back for holding a conversation about himself and replying to himself (2 different BBS IDs) and thanking himself for being such a helpful and standup guy to the community. I believe Skuzzy checked the IPs and then banned him.
What you ask would, IMO, just feed the negative aspects of this "community" -- oh and I detest facebook but also in general do not think we should use that as our ideal online community.
