Well-funded instant messaging and sharing service Meebo is annoucing a new product tonight that will offer loyalty programs and website recommendations for frequent visitors to any site around the web.

The new Meebo MiniBar, not to be confused with the drastically overpriced hotel fare, is a free way for users to choose to share the sites they visit with their friends from various social neetworks including Facebook, to discover related sites frequented by people with similar interests and to gain VIP status on their favorite sites. The technology will be available on Tuesday and will roll out over time to become visible to the 180 million unique users who visit a page that uses Meebo monthly.

Alex Iskold announced on the OpenLike Google group that GetGlue would introduce OpenLike V2 to the public at TechCrunch Disrupt.

OpenLike V2 will allow the user to leverage Facebook Open Graph Protocol to customize which buttons will appear for different type of content, including news, movies, books and music.

A consortium of companies including Google, Yahoo, MySpace, Meebo and more announced tonight that it will launch a new system on Monday that will let website owners discover which social networks a site visitor uses and prompt them automatically to log-in and share with friends on those network. The system is called XAuth and serves to facilitate cross-site authentication (logging in) for sharing and potentially many other uses.

Facebook and Twitter, the dominant ways people share links with friends outside of email, are not participating.
