How do you define MMO expertise?

MMO expertise is hard to define nowadays. See, back when there were three or four titles in the genre, it was easy (if time-consuming) to style yourself as an expert. In 2013, there's a new MMO released every other week, and so it's quite challenging to keep track of them all, let alone play more than a handful at a time or know a title's mechanics inside and out.

Massively's writers and livestreamers are mostly generalists, with a couple of exceptions, meaning that we play a huge variety of games at the cost of knowing everything there is to know about one or two of them.

What about you, comment crew? Do you consider yourself an expert on certain titles or on the genre as a whole? How do you define MMO expertise?
