TechSoup's NetSquared mashup challenge pays out a total $100K this year to the best of 122 submitted projects.

I'm going to have way too much fun browsing through the project proposals. Casting my votes, though, is already proving difficult... Using user downtime? Massive mashup calendars? Warnings for hidden corporate abuses every time I make an online purchase?

Ohboyohboyohboyohboy.

And of course, many of these envisioned projects would not even be imaginable were it not for widely available and mostly reliable government information data sources.
