Conduct a search for literally any letter in the alphabet. Try a search for [s] in Google and the number two result, at least for me, is a Twitter username/profile.
Most single letters come up on the first page. Try [a], [b] or c], all on the first page. Not every letter is on page one of Google, but many.

Funny you should mention it - yes, Twitter profile names do seem to be ranking better.
Twitter, the next Wikipedia?
