@Ronald I was thinking about that. Obviously if there was a way to hack it so you could follow/mention across platforms like twitter it could be a win.

One little hackish way to do that is if you could link to your twitter account. If you mention someone on twitter it posts the text here but then shares it on twitter with the actual mention. If all posts were duplicated you could sorta follow in both directions. If someone were to write that it could be a game changer.
