Video bookmarking - whenever you come across a video and wish to watch it later you can add it to radbox. Still under development - you can test it out. Try bookmarklet on any page that has embedded video.

This is very subjective. :)
If other users vote on this we'll consider.

The idea is to make adding videos real quick. In case of multiple videos you can always choose to watch what you want and archive what you don't when you log into the account.

Our Firefox/Chrome extensions would allow selective adding, but for now we don't plan to change this.

Great. Checking it out. I believe you use this for userecho?
