Facebook might be more tied to ad money and I dislike them even more than I dislike Google but they actually sometimes manages to show me relevant ads - and unlike their "bigger brother" most of the time without insulting me and my family badly in the process ;-)
I'm surprised how dodgy the Facebook and Twitter ads are. Maybe this is an Australian-localised thing influenced by all my various blockers and noscript extensions, but Twitter shows me 50% outright scams ('Twiggy Forrest says this is the deal of a lifetime!'), Facebook shows me 50% anime clothes which are clearly not officially made by Studio Ghibli. Amazing that this industry works.
