I'll split the list of services that could be worth supporting with an Agorava-Connector in the future now into a separate topic.
Given other projects like DaliCore may equally consider them, I'll put that here as a brain-dump. Should there be more concrete leads for some of these, I guess we'll either put something up in Agorava-Dev or create an actual feature request in JIRA.
Yelp is another interesting service, especially given its rather vast Business API
