Hi... congrats on the progress of the page!!
I was starting to read what was around and found the milestone, seems ok, if i get any ideas i will try to make a suggestion.
Only one thing i didn't understood, about the Word Processing app, why do you suggest a wiki? Isn't that model a little bit more static than what a web office word processing app should be?
Any way, i will try to keep up to date with the posts.
