As is well known by now, W.Boudville possesses an impeccably positive (four stars) reviews record of a humanly impossible gigantic size. Having reviewed half a dozen scientific treatises a day for a very long time, he probably realised at last that no one can believe he actually reads these books, especially since his ratings are overwhelmingly positive (he likes four stars, probably in a mistaken opinion that an all-four- , rather than all-five-star record will make his record look less absurd).
Could this be an explanation of his strangest ever habit of, once in a blue moon, picking a book or two and slamming it on most idiotic grounds? Just so he has some negative reviews? Today we have another recurrence of this inexplicable pattern: he reviewed two books, one, a computer book published in 1980, which he slammed for being obsolete, and another one, titled Teach Yourself Basic Computer Skills, which he slams for being too basic ! :O
You just can't make up stuff like that. Truly.
