Google has release a new service called Sites. It differs vaguely from Google Pages in purpose. Sites seems to encourage group editing or other wiki-like applications, while Pages serves for more general situations.
I can’t find anything to collaborate with anyone, currently. So I built a personal portal site. It’s bilingual. I’ll add more contents later.
there’s also Google Knol, which is surpposed to be a Wiki.
This is very exciting. Thank you for sharing this.
