People who write comments on YouTube and Flickr are, with very few exceptions, idiots. It irritates me to have a page half-full of stupid comments when I just want to watch a video or look at a photo... Neither site has any option to remove the comments. So, how do I eliminate them?

The following works in Safari:

Download the file from http://kuoi.com/~kamikaze/doc/safari_style.css

Save this file as "safari_style.css" in your Documents folder.

In Safari's Preferences | Advanced, change the style sheet to Other..., and pick "safari_style.css".

Restart your browser.

Now reload those YouTube or Flickr pages, and voilá! No more comments from idiots! If you ever do want to see them, you can open preferences and change the style sheet to "None Selected" briefly, then put it back.
