I've never followed Keith much, but it's a bit surprising to see him come out so critically following his awkward departure from Square. Undoubtedly a great businessman (PayPal, etc.), but I think this was totally uncalled for, especially in public context. What really irks me is that he keeps it going and defends it. I've never been a huge fan of Foursquare, but as a founder, I know my limits in criticizing others' ventures and ideas. My company is my baby. Publicly humiliating someone's hard work is something I think most founders would definitely take personally, so I can relate to Dennis' reaction. This definitely got way more publicity than was necessary, but I think it brings up an interesting reference point in providing feedback and criticism on ideas/businesses.
