I've been working on some stuff with some hombres lately and I am finding that www.writely.com is the bomb ass AJAX word processor for collaborating. Several people can edit a document at the same time. Its delayed by about 5 seconds, which is good enough. There is a kick ass revisioning system that shows what changed, and who done it. There is also the ability to export any file format you want, and you can easily publish your shit with the click of a button. It is absolutely the fucking bomb shits stuff that google is supposed to be doing only... its already here. If you're working alone I'm sure word is fine, but if you're collaborating on something like a business plan or a software specification... then writely is the motherfucking shiznit, my whores. The shiznit. I suggest you try it out. Signing up takes 10 seconds. I'm insanely pleased with writely. Only thing it doesn't do that I need is to import Excel tables, but thats kinda asking alot of a web app at the moment. And knowing how much these guys kick ass, I'm sure that will happen down the line. No I don't work for writely. Its just kicking my ass all over the place.
