Earlier this week I received an email from someone inviting me to join "Friendster", which is a site very similar to MySpace and Facebook. It must be a relatively new site, since it was the first time I've heard of it. Has anyone else here heard of Friendster??? There is also another site called "jaxtr", which I believe is more of a cell phone based site, but still similar in some ways to MySpace. Of the above mentioned sites and other similar sites, what is your opinion? I have my profile on each of those sites.
