Twiddla is an online whiteboard that lets you start collaboratively marking up practically anything: a blank page, your own images, or a website. It was created to solve the hassle of e-mailing design proofs back and forth for comments. With Twiddla, you can do real-time markup in a matter of minutes, without even signing up.
Twiddla does have accounts - it's in public beta, so you can sign up now - but you can start a new meeting without one, and edit your user details on the fly. Once you're in a meeting, you've got all the basic markup tools you would expect: pen, text box, some basic shapes. You can also upload images or browse to a site and start marking it up. Communication during the meeting is supported by a text chat box and an audio chat button.
It might not be as full-featured as some of the more established whiteboard services out there, but it definitely scores points for quick setup and ease of use. There's even a bookmarklet for your browser, so you can "twiddle" any page with one click. Sure, we could find a couple things to complain about -- an eraser and a tool for drawing neat arrows would be nice, for starters -- but we're in a good mood because we just used a functional web service without having to sign up.
