Ideas For A New Site?

I know it’s about time to start up a new website. I keep getting a lot of ideas for a new site, but I just haven’t had the push through, yet. It’s going to be a tech site. While I feel a strong push to start one up, I also know there are a lot of great sites out there already. I think this is making my quandry that much more difficult to deal with.

Should I go with a tech site or try my hand at another type of site?
