Hi. Great to see such a diverse and distributed group of people interested in and using Neo4j.
We have Neo4j at the heart of a some of the trust-hub services and have been using it for the almost 3 years.
We are undertaking a number of areas of graph research and experimentation with Neo4j, I will post separately to see if anyone else is looking into these areas.
I look forward to some interesting discussions on the community site.
