It’s a long story but I ended up at doba.com through Guy Kawasaki’s LinkedIn profile. I liked the concept and was about to register for the affiliate program. Then, I noticed that the registration form, which requires SSN/Tax ID, has to be submitted over http and not https. That’s when I gave up. Thing is, even a popular website (this site has an alexa rank of 5,901 as of this writing) can be insecure.
