To me it sounds like the diary is pretty similar to a blog, which quite a few people have expressed interest in. Some nixers even have their own blog already and I think it would be a good idea to link them in somewhere (probably the forums) since there have been some great posts on there and a lot of information that could help newbies and veterans alike.

I'm not quite sure about crossposting though. I think it might attract the wrong sort of crowd. We might end up losing a bit of our identity that way. This might still happen with blogs, but I think to a lesser extent if any. Another downside I can think of to crossposting is it might create a bit of friction, especially since we're fairly elitist (or at least I really want us to be).
