First Movers

So as Richard pointed out, it turns out that one of my ODIs is already being done.

In general, should this matter? My first inclination is to abandon the idea, since competing head-on with an almost identical concept doth not a one-day idea make -- 1) the competitive element may drain the "click" factor from the ODI, and 2) there's no first-mover advantage to leverage.

I believe the idea of a first-mover "advantage" is usually overblown in most industries -- quite the contrary, I believe the first-mover often succumbs to pitfalls that serve as an example for later-movers to avoid. However, my initial thought is that in order to be a successful ODI, you need to be the first mover.

What do you think?
