RE: Pinterest, Tumblr, etc. : "Web sites like these to escape, destress, perk up, calm down, feel something, not feel something, distract themselves and ... modulate pleasure and arousal." Well-written and spot-on in my experience. Also: "... collecting online is a form of self-expression for people who don’t create." Not everyone who curates can't create but it can be a substitute.
"I feel that nowadays we are in the age of curation, where more and more users are participating into this giant experiment, like never before, discovering that they can express themselves and whom their are through curating the internet for others."
Fred Wilson: "I'm a big fan of curation in these services. Twitter has lists. Etsy has favorites. Tumblr has tag pages. These are all variations of curation in services that have a lot of noise in them." Great comment: "Art stored randomly in a room is a warehouse. That same art curated and distilled becomes a gallery."
The loss of Google Reader is unfortunate. For new junkies, this was a priceless tool that made consumption of a large amount of information much easier. Even Mike says: "I was using Google Reader when I found out Google Reader was going to be shut down."
