I found another mashup web site/service; I purposely avoided the term Web2.0, called PeopleBrowsr.
This site is currently brave enough to be in “open” alpha release of their site. With a recent interview from Scoble caused their membership to skyrocketed.
This site is doing what many who participate in online social networks had wanted for quite some time, plus many more. The coolest things about the site is its ability to ad-hoc’ly open up individual’s lifestreams.
