If you know a site/program that pays you in bitcoins to do something please post it here.
I'll start the list:
Faucet Sites http://www.bitvisitor.com/ - pays to browse sites, stay on the site 5 mins and get some bitcoins (usually between 0.001 and 0.00008) depending on the advertiser bid (very few advertisers right now)
http://dailybitcoins.org/ - you can load their site once per day, fill the captcha and your address (look at some ads) and receive about 0.0001
