This is probably a mess (for anyone but me, who uses those links everyday):
http://resident.dyndns.info/bookmarks/bookmarks.htmldebian,
foren and
help are probably the interesting links. Some good stuff under Hacking (and some weird stuff too).
It is -perhaps- more comfortable to replace the ending html from the above address with json and wget it, then backup your bookmarks, import the json, and then navigate more easily.
The truth is: i mainly use forums and every other day i use a searchengine (but rather seldom). Well: or look in my bookmarks.
I am not too sure this was very useful.
If it isn't, just say, and i can try to make a best-of list and put it in some order (but that sounds like work). I would start with the main debian sites (debian.org, wiki.debian.org, debian-packages ....).That should already be a few.
