Damn, I was going to say hotornot, but you already did. There have been thousands of other startups though that have had first mover advantage work for them in a huge way.
i agree with the article -- first mover advantage only carries you once in a blue moon. The biggest successes today were nowhere near the first ones, they just did it better. Google came YEARS after yahoo, lycos, alta vista, and facebook came way after friendster. doing it better is more important than doing it first.
