As an example sometimes we talk about our policies on managing our classes and our reactions to some of our revolted students here in matheducators forum. Sometimes I think what our students do if some of them see our posts here. Maybe it is not a serious problem for those dark lords who live into the shadow of anonymity but what about the others? Should we keep this forum secret like a medieval hidden brotherhood?
On the other hand one could imagine some possible positive aspects of the presence/participation of the students here.
Question. What are the possible positive/negative consequences of teachers online activities (particularly here in matheducators.stackexchange) on their teaching?
Remark. I am searching for enumerating all possibilities.
