Post Panda I don't think we need all the extra fluff, but keep it merely to the essentials, to make it easier for the visitor to do what they came to do.
If you're writing content solely to satisfy a search engine, that might be fine and dandy.
If you're writing content to convince humans to buy, it's another thing altogether.
The whole Google line to 'write for users' vs. 'what the algo actually does' is counter intuitive.
The eggheads at Google don't seem to understand that real humans require constant bombardment to convince them to buy one widget over another. If you think I'm wrong, then tell that to the automakers who spend billions every year repeating the same message "buy our car" over the air waves.
If Google owned the FCC, on the free air waves they'd limit repetition and you'd hear one ad for one product each week, and that's it. Might make it a better world for those who hate commercials, but a miserable world for the sales force.
There would be one channel however, the Google owned AWORDS channel, and that would be allowed to repeat product messages 'ad nauseum'.
"Fluff" in many cases sells. Without it, users feel lost and left with an incomplete story. The new algos might work nice for the true, obvious blackhat cases (and they should!) but when they go rogue and slam a site just for doing their best sales schtick, then it's a shame as this impedes the eCommerce of the planet and the prosperity of honest people.
When we win, Google wins, when we lose, um, well...Google wins...so I guess it just doesn't matter now does it?
