Maybe it's just me, but I lost some of my enthusiasm for sticky threads when four stickies took up the whole first page of threads in a favorite forum.
But I realize that may still be desirable for infrequent visitors to that forum. And it grows the site more if new visitors see great things right in their faces as soon as they hit a forum. It's easy enough for me to "Page Down" even if I hit that forum several times per day.
