This morning I spotted an email from my local theatre that was too good not to share, as it appeared to be selling off a comedian. As you do, when I tweeted about this I included the Twitter address (handle? ID? none of them work well) of the comedian in question, Ross Noble, and I noticed that, like a fair number of famousish people, (presumably the ones that aren't rich enough to buy the person who already has, in this case, @rossnoble) he has resorted to putting 'real' in front of his name, making him @realrossnoble. There are plenty of others - David Mitchell (the comedian, not the novelist) is @RealDMitchell, for instance. I assume this has happened because someone else called Ross Noble, David Mitchell (still not the novelist) etc. has already snapped up the simple form, like my @brianclegg. It's fine, obviously, to modify your name to be both memorable and still clearly like to your name - much better, certainly than @rossnoble99 or @nobleross. But...
