Do You Have Enough Subject Classification Tags?

Really, Alex and Alan? Are 19 separate classes in the Mathematics Subject Classification truly necessary? Don't you think that's just a bit extreme?

There is nothing wrong with this, but you've managed to win my WTF award for the day. (That said, this paper now makes me wonder if this is the record.)

In summary:

(a) That seems a bit extreme.
(b) I wonder if this is the record.
(c) Seriously, WTF?


Update (1/14/13): One of my students checked the data that we have, and the maximum number between 1980 and 2009 appears to be 8 secondary MSCs (the one above has 1 primary MSC and 18 secondary MSCs). Wow.
