What is the relationship between Leo Laporte's http://twit.tv started tech network and the newish http://thisweekin.com started up by Jason Calacanis? Looks like http://thisweekin.com leeches on the concept put forward more than 5 years ago by Leo.

Jason has been on Leo's show numerous times and I'm sad to see this happening. I looked in both site's About to see any link between the 2 concepts but see none. If Jason is such a savvy investor why didn't he invest directly in Leo's venture?

What's next? If Leo starts up another "This Week in ..." show, Jason's company is going to sue them for naming rights?

What's more sad if this is true is that I got to the thisweekin.com website vie Jason's ranty email about Goldman Sachs, and at the end of that he describes thisweekin.com as a model of "creating a business" and "angel investing". I call this the "angel of death model". It's creating a business via pirating a naming concept.
