Searching for a blog niche.

I have so many interests that its hard to really stick with one topic to have a comprehensive blog. Added to that is the fact that I rarely stick with something consistently, like writing blog entries. It had been months since I've updated my LiveJournal up until this past week, and those have been mostly private entries for me to keep track of things.

If I was to keep a semi-regular blog... what do you think it would be about?

Then again, I already have about 5 blogs on the go. Plenty of people write individual blogs on seperate topics, why would I be any different?
