Our venture capital roundup for the day features a range of companies raising large and (relatively) small amounts of money. We've got software for school teachers to keep their classrooms organized and an app to make keyword advertising easier for small businesses, among several other useful technologies. We want to know which of these companies you'd like to keep tabs on. And as usual, we're announcing yesterday's poll winner.

Yesterday's poll winner, Qriosly, asks real questions of us on our mobile phones and iPads about products or companies, instead of using a traditional ad placement. RWW voting readers were most interested by this company; it earned 72% of the vote.
