What if I don't have an idea?
unalone: While you're waiting for inspiration:* Find somebody to work with. Do freelancing. See what makes freelancing difficult for you or your clients. Figure out a way to do it better.* If freelancing is a no-go, use web sites. This is what I did when I first wanted to launch a site. Visit every one you can. Sign up for all of them. Make notes of what works well, what really doesn't work at all. When you find a particular TYPE of web site that doesn't have any good models going for it, make your own alternative.That kind of idea is no alternative to having a Great Big Plan, but it lets you mess with things, stay active, and it means when you DO have your Big Idea you have both a little more expertise for launching and you have users who might be willing to spread the word.
