6 months ago my clients site was overhauled and the user generated searches had an index tag on them. I switched that to noindex but didn't get it fast enough to avoid being 100's of pages indexed in Google. It's been months since switching to the noindex tag and the pages are still indexed. What would you recommend? Google crawls my site daily - but never the pages that I want removed from the index. I am trying to avoid submitting hundreds of these dynamic URL's to the removal tool in webmaster tools. Suggestions?

What do you guys do with your old content/news/articles? Do you just leave them on your site forever for historical reasons? It goes without saying that you wouldn't delete an article that has links pointing to it. But if there aren't any links, it doesn't rank and it doesn't receive traffic… do you just scrap it? How say you? Update: I would also like to throw in that I have a client who in 2006/2007 used content from another site. What would you do with that content after this amount of time? Bother with it?
