I found out about Yobongo from a friends tweet. He doesn’t tweet often so when he tweets I click. I went to the website and decided to sign up with my email address (mainly because my buddy tweeted it). After you enter in your email address they ask you to refer 3 friends to get early access into their beta. I thought this was a great way to leverage other people to share on their social networks.
Update: Great comment about yobongo’s execution
Yeah dude they put a lot of pressure on me to tweet so I could get invited. They had a perfectly executed PR stunt.
1. They got techcrunch to give them an exclusive.
2. They then created a special link for TechCrunch readers to get priority on the beta invite.
3. Then once I signed up they put even more pressure on me to tweet so I would get invited.
I was intrigued enough with the product that I thought what the hell might as well do it.
