New York Based Ziki is a new social networking site that allows people to tag themselves and make connections with others through those tags. It also allows users to pull in RSS feeds from their blog, flickr photos, YouTube videos, etc.
It’s Suprglu with social networking added on.
I had all sort of problems registering (and I’m pretty good at registering for new services). Ziki requires too much personal information, such as my birthdate. Also, I repeatedly got errors trying to submit my registration, and never received my confirmation email allowing me to log in. My recommendation: ease up on the required personal information, fix the web form and email confirmation, and slowly encourage your customers to add more content to the site. More on Ziki here.
