I am hoping it is from the PRODUCTS they were demonstrating in Barcelona. It would be great to see revenue in addition to the licensing model.
I recall that Bill Merritt said the service that Wot.io offers is unique, and if I understood him correctly it is independent of the various proposed standards. He said it overlays the various data sources.
If the upswing is because of a license agreement I would like that too. So, I don't know but it is definitely a good thing. IMO
