What I don't understand about Web 2.0: If Technorati Tags are universally held to be a Great Thing, why don't they ever work for me? (And why doesn't TypePad know how to spell Technorati?)
What I have come to understand after reading lots of blog posts on how to increase your blog traffic: Titling a post "How to increase your blog traffic" or "Six tips to increase your blog traffic" will increase your blog traffic.
Another thing I've gleaned: Using the term "Web 2.0" means you're one of the cool kids, and all those Web 1.0 users will eventually be overcome by a superior force from a world beyond. The remnants of their culture will one day be examined by anthropologists aboard the USS Enterprise.
At least the Neanderthals' DNA survived.
