I've searched the tags on SO for a [google-document] tag, but couldn't find one. The closest is probably the google-docs tag. Here people will go wrong if they choose that one. Not only is it replaced by google-drive, it is meant to resemble the office suite of Google in the Cloud.
Given the high number of questions on Google Documents and the very high number of google-apps-script question, that very often use google-spreadsheet or [google-document], I'm in favor of creating that particular tag.
The list below, I was able to tag as a [google-document]. These were only taken from the first search page: https://stackoverflow.com/search?page=1&tab=relevance&q=google%20document
List
- autoCrat naming google documents

edit:
Tag is deleted by: https://stackoverflow.com/users/168868/charles. Perhaps he can delete the google-spreadsheet tag as well. I'm out.
