Well, it least there is any plans? You got to understand that people are used with things like Facebook, other Social Networks that work with Joomla are not so popular, so their features are not so relevant as Facebook is. If we want to attract people from other Social Networks (webmasters for you, users for me) you have to overcome their expectations - little things like this make all the difference.
But... well, I may be saying stupid things (again).
