Over at Liz Vicary's place, FM Jon Jacobs goes off in the comments to this post:
They and their blogs carry colorful handles like Liquid Egg Product, blunderprone, Wahrheit, and even Man de la Maza.
(snip)
Less politely, they could be described as a "cult" - the word I used in my first post here. The clincher is, despite the painstaking effort they pour into both the MDLM puzzle "circles" and documenting their progress on their blogs .... few if any of them are actually showing any chess improvement!
Since Jon-Boy obviously doesn't know what the hell he's talking about, I make a comment with a whole paragraph of bold type. I don't need to repeat it here, go ahead and check it out if you like...
Anyhoo, I must say it was all in good fun, I can only hope he'll stop by here and share his response, if he's up to the challenge of explaining what the hell he was talking about.
