Great, I'm glad you can back up your post with your own data. There are different approaches to LinkedIn and it's good that people can try out what works for them.
Another suggestion for your post: in your first comment to me you said your advice was to move that keyword list to different areas of your profile. In your post, you don't make that suggestion or any suggestion at all. If your advice is to move the list to different areas, you might want to update your post to include that extra detail. Right now it reads as though your advice is simply to delete those keywords.
