This is something new, see their post here. I like to try new things and learn from them. I don't really care about earnings as I could afford costs of hosting and related expenditures on getting online. I also find getting paid could be troublesome as I don't really like paypal.
Techcrunch also featured performancing partners recently here. As what I write about is not popular topics I don't think my place here is that attractive. I can see Google offers me mostly AdSense links about paperless office, who cares about saving trees and use less paper at work?
My posts about management topics are also terribly boring. Also I don't believe anyone will click Amazon to buy a book by Jim Collins after reading about him here.
