how i described arena to my mother last night:
"its a platform for doing research collaboratively"
"an easy way to share knowledge especially if you have a large volume of links, images, etc."
"a single chunk of info -- whether it be an image, link, video, text, whatever -- can be used and reused in any number of collections. and when you do put a particular chunk in more than one collection, it starts to create connections among them, which shows you the context and can spur ideas"
"those collections are sort of like playlists" etc.
she was like "what about google+ hangouts for working collaboratively" and i was like "uhh no"
