Timeline eradicator for Facebook, YouTube, etc. in Safari

I migrated from Chrome to Safari and I’m looking for an app or stylesheet that eradicates the annoying parts of Facebook, YouTube and other such sites.

The only thing I’ve been able to find is this stylesheet:

I added a couples line to hide YouTube’s suggestions on the homepage and on the right-hand side, which resolves the issues for the my most common distracting sites for the moment.

What do other folks use?
