I use a Chrome extension called Google Search Filter which solves this exact problem - https://chrome.google.com/extensions/detail/eidhkmnbiahhgbgp...

It lets me sync my config accross multiple machines.

Has nice hacker-ish config. Basically a text file you can share with others. This is my current config:

# Make these domains stand out in results

+en.wikipedia.org

+stackoverflow.com

+github.com

+api.rubyonrails.org

+apple.com

+ruby-doc.org

+codex.wordpress.org

+imdb.com

+alternativeto.net

# SPAM - never show these results
