Have you ever seen anyone with the same username as your usual e-handle? Have you ever wondered if you've registered yet at some social networking site? Wonder no more, for the Username Check has come to your rescue!
http://usernamecheck.com/ This has me wondering several things. First, who registered my normal handle at eBay? I'm pretty sure it wasn't me, as I never even had an eBay account until late this year (and I didn't try to register it under my usual handle, come to think of it). And second, the Yahoo! person with my e-handle might be me, though I don't remember. Maybe. I'll have to check.
I'm now half-tempted to go grab my name under the really popular networks before someone else does. You never know, after all. Except Myspace. Ew.
