Ask HN: How do you share photos?

Having just been on a vacation, I have mid-sized (~200) collection of photos I'd like to share with friends and family.

There seem to be a bunch of sharing options out there, which one do you use?

I need a network that either the recipient doesn't need to use, or is likely to be using already (aka Facebook), where I can control specifically the list of people who see the album, and where I can choose a couple of different subsets to show different groups of people.
