WESTCHESTER COUNTY, N.Y. (TheStreet) -- There Amazon (AMZN) - Get Report goes again. If generality is the enemy of art, it is also the enemy of stock prognostication, and Amazon is the General of Generalities.

Here's what Amazon always does: the company says a product is selling like hot cakes or ten times better than last year. But it gives no specifics. Ten times better than what? Amazon rarely says.

That's just what happened Monday when Amazon trumpeted Kindle sales. Worse, the business media, to their everlasting discredit, just played along. Granted: every instinct tells me that the Kindle--especially since the introduction of the Fire, Amazon's lower-cost answer to

iPad is selling well. Still: there is the matter of magnitude.

Amazon said that Kindle Black Friday sales were "the best ever." First off, I should hope so. Kindles have only been around for a few years. If growth has already stalled--well, words fail me. Moreover, the Kindle Fire was only recently introduced. It stands to reason that it would help Amazon achieve its "best ever" Black Friday.

But how good was it? Amazon tells us...in its characteristically maddening way. Customers, they said, purchased four times as many Kindles this Black Friday than last. But four times more than what? Amazon didn't say, which renders the information nearly useless. Worse, Reuters does not even mention that Amazon didn't deign to mention the baseline number.
