Well. Facebook & sites like that are about functionality. Blogs & forums are about discussion. In my opinion, any flashy stuff is just icing on the cake. I'd be bothered if the site didn't do the basics in a stable way (i.e. few crashes), but if I can't put a picture into my post I don't really care. In almost every case, that ability would add very little to whatever point I was trying to make.

All that said, it's very possible that Benjamin is planning some other functionality that will appear later. You forget he's had less than a year on this site. Mike had more than 10 years to pull things together.

Be patient.
