If I create a public Google Doc that anyone can edit who has the URL, will my Google id or name or anything else be publicly viewable?
I tried it and I didn't see anything about the owner in another browser without being logged in.
The document must be shared either with the setting "Public on the Web" where it will show up in Google Search results, or "Anyone who has the link". Either way you cannot find the e-mail address of the owner of the document. That would be a great security loop-hole on the side of Google, since anyone will know what company is doing a survey on what and stuff like that.
