thats a good question and have a few pages I want to shit can on my LL also, I was gonna just change the page into another category and let the spiders do there job
my misc page I am thinking about getting rid of, and that ezine page that made me 25.00 in 3 years
imo I think it hurts a LL in the engines to have pages that never change and get new links = content, or pages that dont change and/or have a bunch of aff links...
