i found livejournal.com to be a great way of keeping an online dream journal. its worked very easily, so the simple minded should be able to use it no problem, its easily customizable, you can add friends, and you can comment. i just thought i'd let everyone know.
heres a link to mind for an example: http://lucidjournal.livejournal.com/
add me as a friend if you'd like :)
