There are 10 sticky threads currently in lending section.
I'm a little confused why some relatively new deposit taker e.g hashking has his thread stuck while other older members don't.
Stickies only go to people with lending operations, since that's what someone new to the section would be looking for. Otherwise, they would get buried in all of the lending requests. Everything else is covered by the "Who pays what?" sticky.
While you might think that it'd be better to collapse the threads into one, that will only ensure that those threads are never read, because "Guide to (anything)" stickies are universally ignored.
