Judith Meskill notes an article at Time.com called What Are Friends For (Relationship-Capital Management – The Social Software Weblog – socialsoftware.weblogsinc.com):
Deals vs. dates? Is that the difference between LinkedIn.com and, say, Orkut.com? Not really. But it is the difference between a LinkedIn, Visible Path, Spoke, or Ryze and the top dating sites.
The Social Software Weblog also has a spiffy new design. Kudos to the Weblogs, Inc. Network for the upgrade. I find the new look much more soothing than the old one.
