What about noindexing Wordpress category and tag pages, as well as a robots.txt file? Anyone seen a jump after implementing these changes?

Why should noindex them? Some of my category pages get 500 visits per day..
I also get visits to pages 2-3-4 of these categories.
+ with a very good bounce rate and page per visit.

I never used Tags and think that if you have categories you should avoid tags but if you have tags don't use categories.
