"Paul Graham has a nice article on how to start a startup up but does not get into defining the term technology startup."<p>I'd already covered that here: <a href="http://www.paulgraham.com/wealth.html" rel="nofollow">http://www.paulgraham.com/wealth.html</a>
It's probably easier to list a few things that are NOT technology startups (at least in 2009): consulting company, staffing company, technology product resale company, ecommerce site.
