Radar, which focuses and helping groups of close friends share photos mostly on phones has added a new sharing feature. While Radar's focus is still allowing small groups to share their private moments, Radar now allows you to share those photos that you don't mind everyone seeing. They've got the necessary widgets and stuff to make this easy too.
I invested in Radar because I think that the small group co-presence sharing is different from "publishing" like this blog and that this market is still underserved. However, I do think that there are some moments we all want to share and think this shift is a good direction for Radar.
It will probably get me to use it more too since I tend to be... *cough* slightly more "open" than the average person.
