A couple of weeks ago, one of those Fools, All-Star BlacknGold, touched on Carbonite's seemingly unsustainable valuation:

With a fair book value of $0.78 this company is greatly overvalued. The red ink continues to get darker each quarter and shareholders' equity stands at only $20 million as of 1Q12. Furthermore, their product is easily replicated (no moat or competitive advantage). Should be an easy red-thumb target.
