Thinking Of Starting An Internet Business? Check Out These Two Models

I often get people who run their ideas by me for an Internet startup. Sometimes the ideas are good while other times they aren't.  However, with the Internet, you never know what type of website could or couldn't take off.  So, I have always focused on the business model and business type behind the idea when relaying advice to others. 

You may remember the website PleaseRobMe.com which launched in February of this year.  The site basically highlighted people who checked into to a given location on Foursquare, thus notifying others that they weren't at home and could be robbed.  Seemed like a random idea, but after being featured by
several tech blogs including Mashable, the site took off and it spent a few days in the Alexa top 10,000.  The service has since been deactivated most likely due to the public outcry and liability that came with the offering - but its growth could not have been predicted by anyone.
