Patricia,

Actually, you can limit the ability of others to write over what the author of a G.Doc has written.
I used G.Docs in an online course last winter. When you give access to someone else, you have a choice of whether to give them (a) viewing access which includes posting comments but not editing the original document, or (b) editing access which does allow them to re-write the original document.

You can set privacy limits on Google docs so only those individuals who you
specify can access the document. You cannot stop those with access from
writing over someone else, but you can view the revision history (under
File) and see who has edited what.
