Twitter unveiled a new logo today and I must need another cup of coffee because I needed a lot of help to see the difference. Thank goodness for TechCrunch, which breaks down the differences thoroughly (“haircut, sleeker, upturned beak”) and characterizes the logo as “optimistic.” The before-and-after image at left is courtesy of the site.

Twitter describes the new logo’s origins as such: “Our new bird grows out of love for ornithology, design within creative constraints, and simple geometry. This bird is crafted purely from three sets of overlapping circles — similar to how your networks, interests and ideas connect and intersect with peers and friends.”

After the jump, we have a short video about the logo. What do you think?
