People lost interest, I lost motivation. Perhaps more to the point, the people who needed to be contributing in order for this thread to actually function as a guide for everyone else, i.e. the ones who know what they're talking about and can back it up with experience, stopped posting.
As a side note, I happened to think about this thread the other day and I wasn't convinced that finishing it was even necessary anymore...
That said, I'm always willing to get it done just as soon as everyone else is, which is, like, probably never XD. I dunno. I have some spare time this week. If I think of it I'll get something done, even just for the sake of justifying the “work in progress” part of the title.
I mean, I could always just go ahead and write it all, but I've never felt that I would be justified in doing so, and the last thing I'd want to do is write up incorrect or misleading information, especially in the context of a guide. And that's why I stopped writing once I stopped getting input from the right sources. I knew this was likely to happen and that's why I had originally planned it to be a project for the tbr.
