Frankly, I'd do the post a disservice by attempting to summarize it, but I'd also be doing it a disservice by carving it up piecemeal here and commenting on it. One aspect of the post of note, that I really found both interesting and a trifle challenging to my own preconceptions, is his deconstruction of the notion that 25 man raiding is logistically harder than 10 man raiding. His points about how 10 man raids can often be far more difficult to run if even one player misses a night is valid, and he goes through all the ways 10 mans are limited by their smaller pool of players in a thorough and convincing manner.
This is in service of the main point of the piece, which again I think deserves your full attention. He makes the case that the problem isn't logistics at all, but rather that due to group composition constraints 10 man raiding simply can't be as complex, strategic or difficult as 25 man raiding, and so it's not an issue of logistical difficulty, but rather purely inequality of design. In other words, 25 man raids are generally harder than 10 man raids because they can be, they don't have to be designed to be completed with limited group compositions. There are 34 specs in the game, and 25 mans have more room for more options than 10.
Again, this is summarizing a really well thought out piece. You may or may not agree with it, but please go read his argument and don't just rely on my brief on it -- by necessity I'm missing a lot of subtleties here.
