A few weeks ago someone--I think it was Bob--suggested that I add tooltips to the download links on my
downloads page, to help newer users figure out which format to download. I thought it was a great idea, but didn't know how. Now I do (I looked at the source file for
xkcd), and I've added them.
If anyone would like to check it over and tell me if you think it's helpful--or suggest any alternate wording or useful information--I'd be grateful.
