No matter how good the software is, it's a short-term advantage. It gets you a ticket to the game but confers no sustainable advantage because the good bits will get copied. What matters is what you do on top of that software to build sustainable advantage.

(To be clear: I'm not referring to something like Windows here. SE is obviously complex but it isn't as complex as Windows. Much easier to copy and innovate around.)

I see it as a race now. You have to get that question and answer up before the other platforms do, to lock-in the Google advantage. You'll be leveraging your existing expert network in a sideways drift. Those experts already answer questions madly (and there are very few on the web) and now they have to battle to get their idea off the ground. Good plan. :)

You are missing out those snowflake sites (sorry Patrick) where the expert has zero SE cred but is the world expert on model trains just as model trains become the next bing thing. Still, over time you should have a reasonable monopoly on people who desire karma.

Unless someone comes up with a mechanism that can a) leverage karma whores better and b) discover and resolve hard topics faster.
