Hey, I totally respect that Ficbot!
Actually, I'd be a bit suspicious if you reviewed outside your preferred genre(s) anyways.
Now one idea you could do is to pick up a couple other reviewers who are into those different genres and add them to your list of reviewers. That way you'd have a nice rounded staff of reviewers who could cover the vast majority of genres and make even more people happy.
That's what I did at Raiden's Realm (
www.raiden.net) when I was the owner. There were certain types of software I enjoyed, and others I didn't. The same went for hardware as well. But my readers wanted a wide range of reviews, so I simply found people who liked the other areas of interest and had them do reviews and writeups and articles that fit that area, and in the end I had a nice, well rounded site with a nice mix of authors and opinions.
And having done it successfully myself for 3+ years, I know you could do it if you wanted. Heck, I'd stand behind you if you did. (*big thumbs up*)
