I agree with the above. I posed the question because it's an interesting question on how does a startup (or band) maintain its base of loyalists - especially if it stops evolving at some point. Comparing the two, I think (we'd hope) that technology will evolve enough to replace itself quicker than something like classical music. But, at some point, perhaps it won't or there's a app that can last. For instance, I'm interested in how CraigsList can keep its foothold / loyal followers? Sure has done an amazing job so far.
