You could post pictures of your girlfr... no, someone does that already.
You could post pics of your rockin' mixers... no, someone has that market cornered too.
You could conceive numerous sitcom-y ideas that never come to fruition... someone already does that? Fuck!
You could supposedly engage in political conversation and then do nothing but sling ad hominems under the premise of "debate"... wait, that's a large subset of the entire internet
You could say threads would be better if no one else posted in them. That hasn't been done has it?
Hmmm... maybe you should just stick to the status quo
