I think that the students flamed the teache n their blogs because the teacher disciplined the student and they were angry with their teacher that why they flamed their teacher on their blogs.No I don't think what the student was a responsible thing because thet did not realise it was for their own good.They can tell the the teacher not give them too much homework and not to discipline them.I think some benefits of blogging are they can improve their language.i think the risks of blogging are to talk to strangers you can avoid them by not to replying them when they talk to you.
