How do you know you’re looking at a Web 2.0 site?
Well, check the Web 2.0 Checklist, of course! Heh. I’d add to the list that if you saw it on TechCrunch, or if Tim O’Reilly wrote about it, or the Web 2.0 Working Group site has it, it’s probably a Web 2.0 thing. By the way, Tim has an interesting series on his blog about how alpha geeks got into computers. How did I? I was in Hyde Jr. High’s first computer club. That was 1977. I helped unpack our first Apple II computers. With cassette tape drives! Ahh, those were the days.
