The success of Flickr and YouTube make me think that the next time I think "Wouldn't it be nice to have..." something for my electronic life, I should just go out and build it, especially now so many building blocks like storage and processing are available on-demand. I've been thinking for years now anyway that I want to stop working for large companies and chart my own course for something. I was all set to take a break and start considering what my venture would be at the end of April when my time with Nokia would end, and then this gig came along.
I have no experience being an enterepeneur, though, and no idea how. I'd just build something with as a little customization as my UI persona can get away with and stick AdWords on it.
