I was a little disturbed by this. Maybe this is common knowledge to everybody else, but I wasn't aware that I was exposing my gmail id by viewing a google spreadsheet. If you go to "spreadsheet view", there's a drop down list of all the people who are viewing the spreadsheet now. Those are their gmail id's, for all to see. Since I personally try to protect my gmail id, I thought this was worth mentioning.
