The future is here. You no longer have time to adopt a "wait and see" attitude. Trying new things should still be high on your list, but only if you are ready to examine the results and react quickly. And by quickly, I mean within days; not months.
This goes against the "let it soak" approach business has taken toward the online space. Well... we were wrong. Or rather, there exists better approaches today. Adopting the Fail Fast methodology requires more effort up front. More planning. More analysis. More understanding of what you're doing. And what you expect to get in return.
It doesn't mean start small. But it also doesn't mean you have to go all-in. Size is only important if your upfront analysis indicates it might be. Yes, you can learn as you go, but you have to adapt as you go. Data puke gets in your way. Get rid of it. Focus on the goals and objectives you set forth at the start. Ignore everything else. You don't have time to spend chasing down interesting blips. Not yet, at least. First, you have to fail fast -- or hopefully succeed.
The era of learning and not doing is at and end. Welcome to 2010.
