I’m shocked about InstantBuzz
I've been offering some of my InstantBuzz invitations to people visiting this blog, and a few of my favorite forums.
I thought I was doing these people a service by allowing them to be able to get their own InstantBuzz account, but it doesn't look like they appreciated it very much 
The problem is this: Only 30% of the people that I sent the invitation to have actually taken the time to sign up
Now, a 30% signup rate would normaly make me ecstatic, but in this case it's 30% of people who had already gone through the trouble of PM'ing me or had filled out a form with their requested signup information.
Either this is a frightening example of why so many people fail to make any money online - lack of action, focus and determination or it's a sign of how bad this whole spam/antispam situation has gotten - false positives, undeliverables and overzealous ISP's that will start filtering your email for you without asking first.
Now, I still have some InstantBuzz invitations available and you can get invited to join just by heading over to this form, giveme your first name, last name and the email address you would like me to send your InstantBuzz invitation.
But, only do so if you are absolutely serious about using the InstantBuzz toolbar to drive traffic to your won site and/or will be promoting InstantBuzz yourself.
