A lot of libraries use widgets on their pages to answer virtual reference questions. They use things like Meebo, Digsby, AIM, and the very cool Library H3LP. Yet recently Meebo co-founder Seth Sternberg, one of the pioneers of widgets on the web, pretty much said that widgets suck. His argument was that widgets can’t be easily updated (you have to copy and paste in an entirely new widget) and that they take up a significant amount of screen real estate.
For possible downsides, because it is all hosted on Meebo’s server it could be changed at anytime. They might decide one day to include ads on all their bars. Though I think their current model of opting into ads for a small cut of the revenue is working for them. But other than that it seems like it could be the next generation of service for libraries providing virtual reference to their members. I made a quick screencast demoing an example of what a library Meebo Bar could look like. If you want to play with one yourself, you can visit their website or see it in action over at Slate.
Is anyone currently using this? Would this be something that could be useful at your library?
