If they weren't so overplayed it wouldn't be so bad, but every microbrew has like 3 IPAs, 2 dry-hopped pilsners, and a seasonal novelty that if you're lucky is something noticably different like a wheat beer or a porter.
I brew my own as well, but I think I only brewed an IPA once or twice (I got black IPA once by accidentally being too liberal with my hop additions). Never saw the need for it since I can just head to my local beer store, throw a stone and hit an IPA.
