I'm so glad that Twitter have updated their logo. I can now sleep at night, confident in the knowledge that they have improved their brand image so much!
But, perhaps the joke is on me. Twitter would probably know that a small change like this would attract attention on the internet. There is no such thing as bad publicity, as they say.
Or, maybe the original logo is intended to reflect a fledgling company and now the new bird represents a more mature company? If we follow this natural progression, perhaps in a few years it may look like this!
