Sad to see it end this way but with the recent news about bestmixer and all the other shit going on I completely understand the decision and don't blame them.
Very sad indeed. Not only the loss of a great sig campaign, but also the loss of a great bitcoin blender. I really liked Bitblender, there were some great features, like the auto withdrawal with multiple addresses and timed, random releases. It's really too bad, I'll miss the service.
