tldp is a bit of a misnomer really, if you check things out there, you'd notice that the main focus seems to be to compile howtos etc in one location, searchable and in a common format.
The actual language used isn't always as straight forward as it could be. I usually presume that because "penguin heads" tend to know a fair bit as to how their system works, they seem to require a fair amount of "prior knowledge".
I'm sure you know what I mean, if you're trying to do something thats completely new, then you really need access to docs written in a "monkey see, monkey do" sort of way.
It's my impression that those who have a good grounding in linux knowledge wouldn't necessarily need docs written like that, but then again, they'd probably skip read it to the relevant bit's that they need to find out.
The docs i've linked in my sig, well theres loads of info there, but again, it's not always that easy to take in, especially when you're playing "hit and miss" to see if the "whatever" app you're trying works in a similar way to something else you've used previously.
I found the "how to read man pages" helpful, because the man pages have just about everything you could want, but if you can't decypher the format of the info, then it's about as much use as a chocolate fireguard!
It can also depend on which distro you're using. my current mandrake install seems to have a fair amount of specific stuff, but it can take a bit of digging through.
Whereas, say gentoo, well if you surf for it, then you'd come across the gentoo forums and the handbook. Both full of stuff that may, or may not help.
Ha, sorry, that probably doesn't make it any clearer!
