If you want an easy, well-known way to share photos that's integrated into the rest of your daily life - then go for it with Facebook. But I never know if my photos will pop up somewhere I don't want them to. And granting access to my photos to people also in my Facebook network can confuse things. And I'm liable to mess up my entire privacy situation then. Also, I don't like how hard it is to recover the high resolution version of photos once they're on Facebook. But one upside is that you can just throw SO many photos on Facebook and they'll never stop you.
