* Not every website is a startup. I don't really see anything startupesque about the site.

* I can't figure out why I would use this rather than Reddit, Hacker News, Digg, or one of the various StackOverflow sites.

* "You cannot collabrr at this time" Just call it posting already.

* Links on one page are the same color as non-links on a different page.

* I find the interface in general to be clunky

* I'm not sure what you mean by "drag" content during post creation. It didn't work for me in Google Chrome at all.
