I'm not, surprised it's still around.
MMOs in general are very good at investment/achievement trapping users. SecondLife also is but their users will spend pretty large sums, I've seen users some 3 grand in (before land), owning small amounts of land will cost thousands up front and a few hundred a month to keep it going. It's going to be hard to leave that behind.

I played for a summer between highschool and college. Great fun for a student in IT or some sort of graphic design. When I cashed out for the start of the school year it was enough to cover college books (not a lot for the time spent, but better than my friends got from Warcraft).
As a 19 year old it was also great for meeting older generations on equal social ground, and picking up some freelancing habits when the risks were less than $100 or so (and nothing but hobby time for both parties).
