What seems to be missing from a lot of online business models is the balance between function – does it work – vs. perfect – is it best of breed/do everything you ever wanted/beautiful.
It might be alarming to some, but functional is always better for a business. Perfection is too costly for 99.99% of the businesses, especially start ups.
Most of the bells and whistles I see Internet media folk put on stuff are completely worthless to the function. Avoid this at all costs.
Maximize this statement: what is the least amount of energy we can expend to generate the consumer behavior we desire.
After a product reaches critical mass, then you can spend lots of time eeking out perfection and small gains.

I agree, well said.
