Hell, we love AJAX, but come on, there's a heck of a lot of people desperately in need of a good old 1999 technology spike in the arm. The term "Web 2.0" in many ways smacks of just this desperation.

", I felt compelled to share. And having suffered a bit at this one, I think my favorite was #5, "Avoiding tables, when they are the best solution".
If you're really in a cynical mood (temporarily of course), you could also check out the Web 2.0 Generator, where in a matter of seconds you can generate an entire Web 2.0 Company
Hey that's not bad. Sadly, they did build their generator with ASP.NET, which is like sooooo not on rails man.
