I wouldn't presume to tell people how they should/could write --- I have my own style and it may not suit everyone --- but I did put together an introduction to writing a journal here
http://www.musicbanter.com/album-rev...c-journal.html with the basics. Don't know if you've seen it.
I think too few people would be interested, or at least continue to have an interest, in a thread about writing journals. Few enough people run them, even fewer maintain them; it just wouldn't be practical. That's what I think, anyway.
