I use twitter for information. Example - I follow our local newspaper which always has up to the minute stuff posted ( Monroe and Stevens closed due to collision) things like that. I do follow a few friends who post entertaining life comments.

Facebook - I'm pretty picky about who I'll friend, but that line is starting to blur with all the women's biking activity I'm involved in this year. I use the "restricted access" feature a lot for people who want to friend me but that I have no interest in allowing them to see my stuff. Lists are a really good way to organize who sees what if you care to manage your list like that. I made a pages feed for the pages I want to follow - local businesses and organizations mostly. You have to follow George Takei's feed and Humans of New York. Most of the organizations I am involved with use FB as the primary form of communication.

Blogs, I follow a few, mainly gear reviews and sports related. Again, I like information much more than experiences. I use the Newsify reader on my iPad.

I do not use or follow instagram although I see things through other links.

I use pinterest strictly for personal idea collecting and to surf when I am bored.

Except for the Think Progress feed on FB I stay away from poliitcal stuff.
