Another big contributor to not selected:

If you run wordpress and have alot of comments with replies enabled, that will generate alot of URLs with the "replytocom" parameter. For example, if you have a post with 50 comments ..that creates 50 unique URLs that Google will crawl and assign as "not selected".
