Here's another cool feature that's part of Second Life's new Social Profiles: Integration with Plurk, the microblogging social network that's a much-used communication channel among several thousand highly active SL users. In the Profile tab, you just click the Social Identities slot, click Plurk, and that gives you the option to connect and link to your Plurk profile. (Linden promise: kept.) As you can see, Facebook, Flickr, YouTube, Twitter, and LinkedIn are also connection options, and I rejoice at this assload of integration choices. Now I'd really love to see an option to actually display, for example, your Twitter or Facebook updates inside your Second Life Social Profile, not to mention your latest YouTube video or Flickr screenshot/photo. But unless I'm missing it, that option isn't available (but hopefully soon)?
Again, to try it out for yourself, go here and log in with your SL account info.
