Etherpad, resurrected: typewith.me
typewith.me
typewith.me
One of the most limiting factors of Gobby is that access control is virtually non-existent, and it has no integration with any sort of version control. Hooks and scripts are required to hack up source control systems.
It seems like a startup would do quite well to create a service combining Etherpad and SVN (or another flavor of version control).
All that said, Gobby is a pretty fun solution for private collaborative editing. Watching colleagues fix your mistakes in real time (and doing it for them) never gets old.
Otherwise, smooth and no complaints. Maybe custom urls? Then again I'm just lazy and could tinyurl for customizing.
Possibly an IRC like interface (with privs for writing) or read-only urls and read-write urls!
Also, there are custom urls. Just go to http://typewith.me/foo and if that's not a pad it'll let you create one.
