Something's wrong with SauceReader

Today I checked my soon to be disconnected blog (although a friend of mine might be able to host it while I move), and was very happy to see more than the usual number of connections. Actually, twice a bigger number.

Then I looked at the user agent strings… And saw that:

Sauce Reader/1.7 (.NET CLR 1.1.4322.573; WinNT 5.0.2195.0)

1269

So now there’s something weird. Either Sauce Reader is hammering my feed more than other clients. Or, there is another explanation that I’m not aware of. Anyone got an idea?
