Niche Blogging

I’ve been doing some thinking about niche blogging. Right now my blog is all over the place. So I am looking at doing a niche blog. Not sure if I would convert Moose Bites or leave it as some kind of stream of consciousness. The question is what niche to blog about.

I don't want to do a tech blog, too much about work and there are so many of them. If I had enough funny computer support anecdotes doing a niche blog about them might be a possibility. I use to have a lot of hobbies, but really don't have many anymore, except reading. I could do book reviews, but again so many of them are out there and you can get really good reviews on Amazon. I could do one on depression but that sounds depressing and they are hard to do well and you risk fall into self-indulgence. There is always one on the trials of being self –“under”employed.

So any ideas?
