There are two new more working level blogs that have been set up recently. These are more technical discussion areas than this blog. Both allow working group members to add posts and comments (moderated) are allowed from anybody else.
http://globalsurfacedatabank.blogspot.com/ covers work towards a global surface databank. If you know of data sources please head on over and provide leads in the post comments.
http://surftempbenchmarking.blogspot.com/ covers work towards a set of benchmark analogs to the databank that algorithm creators can run their algorithms on to ascertain both absolute and relative performance.
