Possibly, more importantly, I've offered to host anyone in the class who wants to maintain their journal on-line. I can think of several advantages of doing this. Firstly, being a public forum, it might encourage people to be more thoughtful about what they are writing. Secondly, and also as a result of being public, it might help them to commit more to doing the journal, i.e. It's that psychological thing of making a public commitment. Finally, it could just be out-and-out fun.
Of course there are some downsides. The system I'm using here, Movable Type, is one of the best blogging systems and it can be pretty straight forward to use–but if anyone wants to customise the look (and why shouldn't they) it can take the notice sometime to get to grips with the complexity of the system.
Oh well, I think I'll just sit back and see if there are any takers.
