This is the other thing that's almost guaranteed to appear for some reason. I think Taliesin did a good rebuttal to it a while back: http://news.ycombinator.com/item?id=3974503
All of this has only a tenuous connection to the language itself, which is much more interesting to discuss. Sure, it may be the only self-named language (thought it arguably owes its name as much to the brand Wolfram Research as to Stephen, and I'd hoped they'd come up with a more creative name), but if one manages to shepherd a system like Mathematica through 25 years, one earns the right to self-name a language.
As for Stephen's ego, I'm surprised it keeps getting mentioned. He seems like a driven person, but then so are many people whose egos aren't discussed. He comes off as quite a decent person in this Reddit thread http://www.reddit.com/r/IAmA/comments/tmutz/stephen_wolfram_... and in this interview with Scoble: http://www.youtube.com/watch?v=mNf8Se_USlE
