I would love to see approximate early growth numbers (first 1-2 years) for social web applications (ideally popular/successful ones, but anything would be helpful). My application is addressing a relatively new market with a large potential appeal (think Craigslist, Ebay, Google, Yelp, Youtube, etc. in their early days), but numbers in different spaces would be helpful as well.
If anyone would be willing to share some numbers for iPhone or Android Applications, I would be grateful as well.
Thanks for the help.
