Actually, I really don't see what is so bad about that.. It's a quick retort, not a letter. Do you really think he should be spending his time worrying about grammar in a reply to a retail shareholder that is already in his second language? I'm sure this wasn't the only investor that has emailed him in the last few days. I'd much rather him write a quick informal response and focus most of his time on the numbers or saving his good grammar for investors whose names end in LLC.
