A bit of feedback - the first thing I see is a message saying "you need to create your account", which put me off. It would be nice if I could save a few things immediately with an auto-generated temporary account, accompanied by a "sign-up to keep what you've saved" message. Otherwise, it's difficult to know whether it's a service I'd find useful.
If I see a big page that tells me "first things first - you need to create your account" before I even know what this site is, you lost me. The next website is just a click away, or in this case, the closing of a tab away.
I've also tried the http://clipboard.com/site/news.ycombinator.com link another HN'er posted here, and I get an empty page. Oh, right, that must be because I'm using NoScript, but it would be nice if you had some kind of fall-back for such a case?
