I voted no, even though its probably the most productive/constructive thing on this website and is definitely deserving of it in terms of content.
I don't check the stickies very often. About once a month I'll notice that there've been posts in Lofi or Yasueh's threads and check up on them. My eyes skip past that section for the most part. I'd try to look more often if this one were up there, but seeing it bumped up to the top of the page brings more attention from people who frequent the forums (the ones answering the majority of the questions). Personally, it'd change my participation in the thread from passive ("Oh look, someone posted in the questions thread, maybe I can help them") to active ("Oh, let me check if anyone has any questions I may be able to help with") - and I am lazy.
My first reaction was that it should definitely be stickied, but I think we're solving a non-existent problem here. This thread is never off the first page. And when it does occasionally drop off, people tend to notice and bump it back up. I think it's working amazingly as-is, no need to change it.
