You are 100% correct of course.
However I do feel I should be able to get in the first 5 pages for "robot-t-shirt". There a just over 3,000,000 results for that search term, and the majority of the ones that currently beat me do not actually [i]specialize[/i] in robot t-shirts.
Other than that, it's viral all the way. Twitter is proving pretty good for that already.
