I have reviewed two of thier products. The first is the LivingPage, a neat way of leveraging the skills of librarians world-wide to build a resource for CSNet and the schools/communities in their family. You can see it at LivingPage.
The second product I reviewed was an exciting vehicle to publish living magazines on the Web. Ceck it out by clicking here VitalZines. It could produce another revenue stream in subscriptions. It is also a product that could be offered over other networks, thus leveraging other infrastructure providers.
