Why haven't you heard of the viral loop yet:
You might wonder how something as profound, powerful, and potentially profitable as a viral loop has remained under the radar for so long. Andrew Chen, a blogger and former advertising executive who worked with MySpace, Hi5, and other social sites, has a simple answer: This critical insight "is worth a lot of money," and the few people who understand it "are all doing their own companies."
Here's my problem. Blogger, Digg, Twitter, LinkedIn, MySpace, Facebook, or Flickr. They have the viral loop, loads of users, have sky high valuations and they don't have a profitable business and no one seems to care about that. Not important, at all.
Reminds me of my favorite cartoon that I along with old friend Brett Goffin used to laugh about as we waited for the subsequent burst of internet bubble 1.0 in 2000.
The UnderPants Gnomes. The "Underpants Gnomes" are a community of underground gnomes.
The Underpants gnomes have a three-phase business plan,
None of the gnomes actually know what the second phase is, and all of them assume that someone else within the organization does.
Watch the Underpants Gnomes Episode, its great. Fast forward to last 4 minutes for more detail on the business model.
This time its probably different though, the viral loop is too powerful, those who know about are so secretive and brilliant they are just withholding phase 2 until the opportune moment.
