This is the kind of foolishness that can cost lives. I don't know your specific situation, but assuming your safe doesn't mean you get to wear an "I survived a Category 4 storm" badge. You didn't. Best case, you dodged a bullet and you should be grateful for that. The point of all the hype, and yes, the media stirs it up big time, is to warn people about what could happen. If Matthew had shifted further west overnight, you might very well have found yourself in a situation where you'd be calling 911 instead of using your precious data to post snarky comments.
The point being, if officials wait until there is more certainty in the forecast, it's too late, and people pay for it with their lives. You don't just evacuate millions of people in 6 hours. I suggest you count your blessings rather than dump on the government/media for crying wolf.
