With the v5.0 release of JFBConnect, we published a 'quick' roadmap for the rest of the year. If you haven't seen it, check out the bottom of our
Facebook for Joomla 3.0 released
post.
In short, JFBConnect is going to start integrating Google+ and Twitter features. JLinked will stay it's own extension (for now), as it's more business oriented, and, frankly, LinkedIn has a very different API than the other social networks. Ideally, I can see having all social networks under one extension, but that won't be immediate.
So, JFBConnect should start integrating more social networks. JLinked will be upgraded to use OAuth 2.0, which is more similar to the other social network requirements. That wouldn't have prevented this latest problem, from what we understand. More features and integrations will be made between both extensions and one day both may be merged into one bigger extension.
We're hoping JLinked 2.1 will be out in late May which will have 1-click registration for users (no forms) and auto-linking to existing users with the same email address.
Hope that explains, but if you have any questions or suggestions, let us know.
Thanks,
Alex
