By whom? I think the only time I personally saw that happen online was in one British newspaper article.
When I stayed with a friend in the Bay Area, I was confused that he said he knew loads of people in SingInst, but kept naming people I'd never heard of - and guess why!

As Risto Saarelma pointed out on IRC, "Volcano Lair Doom Institute" would have been cooler, but this is pretty good too. As the word "Singularity" has pretty much lost its meaning, it's better to have a name that doesn't give a new person all kinds of weird initial associations as their first impression. And "Machine Intelligence Research Institute" is appropriately descriptive while still being general enough.
