In post #98 you stated that I made an assertion that "a completely random match-up of 4 players around a table is likely to be more enjoyable than 4 match made players for any given player". I am still waiting to know where this assertion was made.
As for the rest of your post, I suspect there may be one or two players on BBO who have a poor idea of their own skill level in comparison with others. Some of these would certainly object to playing in games of players at their real skill level, rather than their perceived one, and may play less as a result. I have no idea if zenko would fall into that category, this was merely used as an example while indirectly objecting to the idea that such players were not of an "adequate skill level". I would personally always prefer to play with weaker opponents that were friendly than equal of better opponents who were unfriendly.
Of course the ideal is friendly opponents who are also as good as us or a little bit better. If you want such a game (and are good enough to judge) then you can achieve this by hosting a table yourself and then controlling who plays at the table. The problem is that many players who take this approach boot their partners from the table for their own mistakes whilst simultaneously creating an unfriendly atmosphere. I would personally choose to avoid such tables although perhaps I am also not of an adequate skill level for you or zenko.
