Overall I enjoyed using Google Docs for the resume project. It wasn't too tough overall, but I did encounter a problem. The problem that I experienced with Google Docs was sharing my resume with other people like my housemates. Since I don't use my msu.edu e-mail account, I struggled to be able to view my housemates resumes and to help them out by editing them on Google Docs. If my housemate sent me a link to their Google Doc then I could view it and e-mail them my response, but other than that I couldn't do much more with their resumes on the actual Google Docs website.
When I played with Google Docs a little bit before it was easy because I sent it to myself and enjoyed collaborating with myself, but as far as collaborating with others that was the most difficult part. I think that if the students didn't have msu g-mail accounts than things would work out fine with collaborating as a class. I have heard a lot that the msu e-mail affects g-mail things.
In my own classroom I would have all of the students in my class make their own g-mail accounts or I would create g-mail accounts for all of them and then just make sure they used those accounts when we were collaborating on papers or other projects. I think that it would be a great tool to use in the classroom, because the students would be able to edit each others papers and I could have them submit it to me and I could provide feedback easier without having rough drafts of things everywhere.
If you haven't tried it out than you really should.
