I doubt you could even obtain an accurate approximate estimation. There are tons of ecommerce websites coming up daily that may only ever get 0-5 customers, and it would be impossible to find all of these ecommerce startups. And Paypal causes lots of new startups, since you don't have to pay anything for their credit card processing.
Yeah, that's right.. and also the fly by companies that come around all the time daily, I've seen so many of those that these fly by companies would probably take up 40-50% of all the companies that are around. Kind of bad really and maybe hurts the hosting business making customers weary about other hosts?
