From ReadWriteWeb:
Starting next month, Meebo will be rolling out ads in the IM service that invite users to access quizzes, polls, long-form video and other resources. Users will be able to opt-in to sponsored experiences that are targeted to them specifically, based on their demographics and behavior.
It’s unclear if the ads will carry over to the MeeboMe widgets, which lots of libraries are using to place reference chat boxes on their web sites.
For more on Meebo and other reference IM services, see my article, IM a Librarian: Establishing a Virtual Reference Service with Little Cost or Technical Skill.
