I'm pretty sure most of us come across better in writing, I know I do. Personally I would argue that's a better reflection of the person than the first thing that pops into their head when they're trying to entertain on TV.
I disagree. Writing is a product of time. Give enough time or influence from others and your writing can be whatever you want it be, and it can be far removed from who you actually are.
The same can be said about speech. There's an entire industry on how to be a good speaker. It is very much an acquired skill, perhaps more difficult to master, but very similar to being well written.
