if the posts get really big -and if some get added later on- it might be good to have some strong keywords in there so it'd be easy to do a page search with the browser to find stuff. And if you want to add pics or figures, having separate posts for each broad topic may be better, depending on whether you embed or link, to get around any limitation on pic number and to link to more accurately. But to ensure longevity of the thread, embedding is probably better.
More generally, I don't think that we need to try to cover all the parts in the dang thing. After all the diagrams are there and Onur knows all. But maybe more the main jobs that Mudders are fond of, creative use of non-standard parts, odd situations and the like?
