It is good idea, but I think it would be also good to inform about particular discussion topic in advance (two weeks?)... as participating in telco without having read the material does not make any sense. Here I am thinking more about regular established chats, however spontanous ones are also good idea. In fact, in some months such spontanoues ones could be done more often, as the way of revision.
As refers to me, hopefully, I will be ready will Ethics at the end of the week...
