In fact, as I have only two of them (who by the way know I write on Hive but didn't ask to join), it is not necessary to implement any interaction on a social medium (we have live discussions instead). The fact is while I would be very happy to see my students here, I won't force them if they don't feel that necessary.
What I had in mind was really a project where we could offer to Hive users who are not scientific to participate and contribute to a scientific project. As the level on physics of any "lambda" person may be similar that of my bachelor students, I imagine that this would be something possible to achieve on Hive.
Sorry for not having been clearer on this. Have a good week-end!
