TagWorld Widgets is an open platform and they are inviting developers in to build on top of the thirty or so widgets available now. The developer site is here. The widgets are usable on any website, and TagWorld is heavily promoting the use of the widgets on competing social networks like Myspace.
There are a couple of innovations that make this a more interesting solution than what is already offered by BunchBall and others (BunchBall profile here). Widgets have customizable properties that allow website publishers to personalize them. Things like colors, fonts, speed, etc. can be customized after integration on the website and without going back to the TagWorld site.
I’ve written about TagWorld a number of time since launch – see the posts here.
