Why 40% of Tech Startups leave Atlanta in Three Years

While the paper has some factual errors and conclusions (I do not think that anyone within the Atlanta technology community would call it "rich in venture capital" as an example) I do think that the conclusion that Atlanta's tech sector lacks social structure is dead on. I wrote an article for the local paper to this effect last month: http://blog.weatherby.net/2009/08/startups-are-hard.html
I also think that a main point is missed within the article. Companies that leave Atlanta are not doing so for social structure reasons, they leave because the venture capital factor is based elsewhere and requiring the companies to move in order for a funding event to occur.
