The versions similar to #479 look a bit too much like the AT&T logo.
We're settling on a strong typeface with accompanying symbol that embodies "smart," "quality," "journalism." We're trying to avoid cliches, so we're stepping away from the thought bubble idea. We like clean and simple design, like #303, though some have suggested it might be too "safe." It's close, though there is probably more room to experiment with how to evoke those key concepts in the symbol. The typeface generally works, though you could try some alternatives if you feel another can capture those ideas more clearly.
