1. Girls are just as horny as you are.
2. Those business guys are even dumber than you think they are. (doubly so for the current crop of dotcom guys)
3. What's new is not necessarily better. Do not ignore the lessons (and successes) of the past.
To put it more plainly a lot of supposedly "old" business practices turn out to be the best. I keep on seeing people reinventing things that were common in the 1800-1900's and think to myself "Why bother? That's _just_ a $FOO problem.". Stand on the shoulders of those before you and you have a better chance of success.
