writeLaTeX: Compile LaTeX in a Browser and Collaborate

Just found out about writeLaTeX (via TeXBlog), which lets you write LaTeX "code" and compile it without requiring any software download. The best part is that it is collaborative, which means that multiple people can work on the same document seamlessly.

From the About Page:

• Effortless Sharing – Every document you create has a secret link. Just send it to your co-authors, and they can review, comment and edit.

• Create Beautiful Documents Together – writeLaTeX synchronizes changes from all authors transparently, so everyone always has the latest version.

• Not Just Papers – Make amazing presentations with the beamer package! The preview helps with complicated tables, figures and graphs.

• Real-time Preview – writeLaTeX compiles your document in the background, so you can see the results right away – great for learning quickly!

• Find Errors Fast – writeLaTeX shows you errors & warnings as you go, so you can catch them early, and you don't have to find them in the LaTeX log.

• LaTeX in the Cloud – Edit online from anywhere and on any device. There's no software to install, and no sign-up required.

Sounds exciting!
