I'm pleased to see Senr.net making a difference. Over the holidays, it helped one user capture video of someone stealing a wreath from their door. We hope the guy gets caught because that is such a lowlife thing to do.
We spent many hundreds of hours helping Adam Beguelin create Sensr.net from its inception early this year. We think it is very cool, and love to see it at work. Adam writes about this more on his blog.
