You can let others read your google documents (with a password is an option) and there's a comment button. I'll post if I remember how to do it. With spreadsheets you share the web address and determine the level of security. Others making changes or comments etc.
You click SHARE at the top and click anyone with the link. Then post or send the link. One more setting allows comments, edits ets.
google also offers a similar service- google docs. it's basically a microsoft-word like work surface, but you can access your docs from wherever, provided you have an internet connection. 100% free. but there's no community in google docs, from what i know. you can't share your work and ask for reviews there.
I recently found out about a site called www.foboko.com . It basically sets up a writing wizard for you, where you can write and save your projects, access them from wherever and asking for help from the community when you need a second opinion/help with your doubts and stuff. I haven't looked into it much yet because I've been crazily busy, but I thought it'd be nice to share with you guys. That community idea sounds good to me.
