Take photos what you love and what interests you — and chances are someone else will love it too (and pay you for it) — unless your passion is HDR, then only murderers and Satan-worshipers will love you.
The day StuckInCustoms.com becomes more popular than Strobist.com will be a very dark day for photography indeed.
I hope that day will never come.
Sad to see people down on HDR. I personally love it. Regular photographs bore me. Maybe that's because I'm an artist turned photographer.
