Why do Facebook&#x27;s metrics matter when talking about Twitter? Just because Facebook and Twitter are both social networking sites does not mean they are comparable.<p>Twitter should not have gone public, or at least not at the valuation it did. I think those who invested just wanted to ride Facebook&#x27;s coattails, assuming that a new &quot;social networking&quot; bubble could be created and investing in any such company would be an easy buck. Surprise! You actually need to evaluate a company&#x27;s individual merits, rather than expecting that any Silicon Valley IPO is a guaranteed windfall success.<p>And how in the world does Twitter have 4300 employees? The product should be sustainable with less than 10% of that.
