There is now an official Facebook page for Fringes of Algo.
Recently it became unavoidable for me the join the social networking site (despite my stubbornness ), so I've created a presence for Fringes there. If you have a Facebook account, you can drop by and add Fringes:

We also have a new official Twitter account, although it will probably not be used a lot in the immediate future.
