Really not a fan of the "free for now, we'll give you an idea of pricing in the future". I understand that the team at StackOverflow probably doesn't have an idea on pricing, but it makes it extremely difficult to jump on and try the product.

I guess in that situation, our team should just wait until it's out and public. But a lot of these "free betas" go on for months or even years. I know this isn't always the case, but it almost feels like at times, the goal is to get users dependent on the product before telling them how much you're going to take/charge.
