Open, streams or apps

I like the culture of open problems and challenges to draw out the talented (shy and recluse, or just normal) researchers.

• Piotr Indyk, Andrew McGregor, Ilan Newman and Krzysztof Onak have a nice list of open problems in data streams research. The list has concrete, technical open problems and avoids wordy discussion of novel research directions.
• The FCC challenges researchers and software developers to engage in research and create apps that help consumers foster, measure, and protect Internet openness. A few interesting apps among the submissions, even though they sound researchy.
