This is my new motto (thanks Seth Godin):
“First rule of decision making: More time does not create better decisions.
In fact, it usually decreases the quality of the decision.
More information may help. More time without more information just creates anxiety, not insight.
Deciding now frees up your most valuable asset, time, so you can go work on something else. What happens if, starting today, you make every decision as soon as you have a reasonable amount of data?”

This is the approach that most makes sense for the web. It’s the fail fast approach. Start small. Scrap the things that don’t work. And scale quickly on the ones that do.
BTW, congrats on the blog and the RT (go my first today too!).
