While I'll admit there is some wisdom in that premise in that it's better to actually get something put into place than to do nothing - I also find a lot of Internet marketers throwing a lot of sub-par ideas / sites / articles / ppc campaigns at the wall hoping that something works and not taking the time to hone and perfect one thing that could actually vault them into real profits!
Though the basic premise of the light bulb had already been invented (carbon element in a vaccum) Thomas Edison worked for over 2 years changing the shape of the element / perfecting the vaccuum pump etc. to improve the life of a bulb from 13.5 hours to over 1500 hours. I'm glad he didn't think 13.5 hrs. was "good enough" and move onto his next project.
I belong to a male singing organization that has an annual international competition to judge the best chorus and quartet in the world. Since 1979 The Vocal Majority, a 100+ man chorus out of Dallas, TX has won every competition they've entered (rules require a 2 year hiatus after each win). Many choruses have tried valiantly (and some came very close) to beat them. As such it has pushed the quality level of all competing choruses to a higher and higher level.
Did I say they won every time they entered? Until this year when they were beaten by one of the most dynamic performances I've ever seen.
