I also have a few currently that I'm slightly more passionate which are not on the list. But still haven't found The One True Idea. I do know my general area of interest, though, which is e-learning, personal development, and skill acquisition.
In hindsight, several of "my" ideas have been turned into workable startups (example off the top of my head: Verbling).
I think I have two main challenges:
1) I'm too critical of my ideas.
2) I have a hard time getting started and evaluating my ideas. I would like to be able to create quick mock-ups of lots of ideas and test them quickly against the market.
My strengths:
1) Lots of ideas, very creative
2) Technical skills (programmer)
3) Already have a team in place around the world and locally + lots of potential team mates who I trust
4) Already have execution/management experience on a project (Interesting Times Magazine) - sure, it's not software but I'm still VERY familiar with the entrepreneurial emotion roller-coaster
All in all, this new stance from Y Combinator is giving me some hope for the future. Now I just need to sit down and write a good pitch. How would you guys rate my chances? Any tips?
