We’ve been working on some major improvements to our “also on” feature. In short, “also on” allows you to link your LibraryThing profile to your profile elsewhere, such as Facebook, AOL Instant Messenger, MySpace, LiveJournal, and now Second Life.

If you’ve never seen “also on,” check it out. Go to your profile and click “edit profile.” We’ve got almost 100 sites listed so far. We’re going to be some interesting things with a number of them, but Facebook and Second Life will get most of our attention.

We’ve just added Second Life to “also on.” They don’t have a URL for every member, but we have other plans there!

The Second Life push was inspired by meeting John Lester (SL: Pathfinder Linden) at ALA recently. (Basically, I hailed a guy in a Second Life t-shirt and he turned out to be the operations director of the Boston office of Linden Labs—what luck!) Also, member JPB (SL: Joel CiscoSystems), an amazing Second-Life programmer, has offered to do the “front end” work on Second Life/LibraryThing integration. The “back end” won’t be that hard.

First up will be some sort of program to detect when other LT-ers are near you. When you get near one, LibraryThing and Second Life team up to tell you, and mention a book you share in common.

But that’s just a first step. JPB has head-spinning plans, and we’re happy to help. Come talk about ideas on the Second Life group.
