Takers of the 3rd round of funding! Or 2nd, or fifth, but I'm guessing it's third. Whatever round it is, congrats to Datasift for building a really great service. Their GUI for defining streams is going to be really great once it's polished (definitely a work in progress now, but I can really see how it's going to be awesome), the ease with which they provision new content sources, their responsiveness and transparency when we hit problems or concerns.
DataSift, if we weren't already partners, I'd ask you to marry me.
