If you're tired of reading the inane babble posted in comments on websites, here's a free Safari extension you can download.
1. Visit the Shut Up site.
2. Click the Download link.
Here's a description of what the free Shut Up extension does:
"Steven Frank's shutup.css stylesheet (which removes visitor comments from many popular web sites) is now available as a Safari Extension. The button allows you to quickly enable or disable the stylesheet should you, heaven forbid, actually want to read the spiteful bilge of your fellow man. "
