Dear Twitter web folks,
To me, a favorite means "I like this."
A retweet means "I want my followers to see this."
Recently, you've been sharing things I've favorited with my followers. This merges these two ideas in a way that makes me uncomfortable because I've lost some control of the message broadcast under my name. Favoriting and retweeting are now a single, blunter concept.
I'm sure it increases some metrics you care about, but I believe it also takes a useful distinction and oversimplifies it.
