Standard deviation isn't the problem, skew is. Yes, skew will increase the standard deviation, but the heart of the issue here is how fat the right tail of the distribution is.

Standard deviation is often a useful metric, but it's at least as flawed as mean in skewed distributions because it doesn't treat either direction around the (already flawed) mean any differently.
