I saw a bunch of cool startups at PC Forum. My fave was SpotRunner. Just a brilliant business idea: Resell leftover TV advertising spots to local small businesses.
I had to reverse my initial opinion on Bitty Browser. I went from perplexed to "this has potential."
Most eagerly-awaited launch: the photo search service Riya. I saw this company at Demo, too. See video. Still waiting to get my hands on the beta!
