The one reason Buzz might just click....

…is that it’s within Gmail. You need Gmail. You keep checking it every few minutes you’re online. Google’s bet is that your attention-deficit-disordered mind will want to click on that ‘Buzz’ link.

Remember Wave? You had to go over to wave.google.com . In hindsight, what killed Wave was that it was at a different URL. Its ‘incompatibility’ with something users were familiar with was too much of a barrier.

Anything new faces a lot of friction and inertia. If someone told you to go deep sea diving, you wouldn’t take the plunge right away. You’d hem and haw and ask around and inquire. You’d make sure your fears are allayed before you take a step.

One way to overcome that friction is to build a bridge from the old to the new, and make that bridge easy to traverse. That’s something Goog seems to have done astutely with Buzz.

(and what is the one thing that might kill Buzz? The fact that it hasnt really thought about privacy. And has refused to learn from Facebook's mistakes.)
