The web2.0 feeling

Suddenly you get a great idea for a website, but then you recall
 how hard is to manage real scalable websites and how much money large websites spend on bandwidth, security and maintenance. You realize you have inadequate skills/resources and just give it up. Now you hear about failure of innovation and corporate stranglehold on the web, just remember every little idea destroyed.

If your idea was that great, you wouldn't be worrying about upkeep costs, as the revenue would easily offset these costs.

So, in summary, your idea wasn't all that good after all.
