...or maybe...tweets aren't an accurate representation of an author's mindset? Especially ones in a customer-company relations context responding to a recent account blocking/unblocking? I know I'm always polite when communicating in that context (it does little good to respond in a hostile fashion even if you think the person on the other end is the lowest of the low).

i mean, the blog post might not honest be either, maybe there is another motive, but i'd put the company-directed communications and tweets at about the bottom of the authenticity/trust hierarchy myself.
