It's true, there are no first mover advantages on the web anymore. If you have an idea that doesn't exist already, it's probably for a seriously good reason or it does exist somewhere and is performing poorly enough that you can't even find it after browsing 10 pages deep on a keyword search. What i learned from Ben Horrowitz, was that you need to find something that does work and has current market share (and market size), and make it 10x better. Making things 10x better and going after a defined market is the way to go. Forget the trending discussions of 1995-2005 that consisted of 'finding web concepts that no one had hacked up yet'.
