I'm looking for something fun to work on in the evenings these days. I figured I'd give iOS development a try but really have no idea what to build.

I'm not really too good at graphics so games are mostly out of the question. Other than that I'm open to pretty much anything.

So lets hear it. What ideas do you have?

Just wondering on how the community feels about Google AdWords? It seems like there is always hot and cold recommendations for it. Can you provide real world advice on how effective it's been for you when launching?

Most people you talk to will agree that you need traction or a bit of assurance before you start building a new product and fully commit yourself.

My question for HN is how much traction do you need before you really commit and do you have criteria? Also how much success have you had after said traction?
