I'm also VERY worried about that. My company was just about to use wordpress.com as well, but this limit is insane if true, and means there's no possible way we could even consider using wordpress.com for our company blog. Like you, I have written blog posts that have exceeded 50K visits for one post, and two such posts would exceed that limit. I've done that several times, and it would be crazy to suddenly have a blog hosting platform block viewing of a blog post that turns out to be super popular. For us, it would be fine if they just charge a little more, rather than blocking viewers. However, the fact that they don't say what they will do is a deal breaker. Edit: I see the CEO has posted elsewhere to address this -- "Traffic limits will only be enforced on the honor system. If you consistently go over the cap month after month, we will let you know and ask you to pay a tiny bit more to cover the cost, but we will NEVER shut off access to your site, nor will we ever auto-increase the amount you're paying."
