Former Twitter Chief Architect Blaine Cook was on the Gillmor Gang yesterday.  He must have pretty thick skin to agree to a conversation with Mike Arrington, who mercilessly knifed Blaine in the back as he was going out the door at Twitter last month.

The interview itself is nothing great – Blaine is very careful with his words – but there’s a few tidbits there.  If you’re a techie and afficionado of Twitter, you might consider checking it out.
