DiapDealer: You probably didn't intend it that way, but your "I can assure you" came across as pretty condescending, so I can understand the sigh.
For myself, I have no strong preferences about reading order. Some series I read as they are published, so publication order is the only option. For others, I'll usually look for recommendations, unless the starting point is obvious. For series which are more or less loosely connected stories in the same world -- like Liaden or Disworld -- I might start in the middle both cronologially and publishing-wise. For Bujold's Vorkosigan saga, I started at what must be the absolute worst place: "Memory", which is closely connected to stuff which happened in the previous book, and packs a lot more punch if you know the characters. (That wasn't my intention, I picked it up while travelling and had no idea that it was part of a series.) I still loved the book, and got the rest as soon as I could find them. (That's another example of publishing order being different from writing order, by the way. Bujold wrote Cordelia's story first, then the first book about Cordelia's son Miles, but sold Miles' book before Cordelia's books.)
When I reread, I can start anywhere, including in the middle of a book. Often, I'll read a favourite scene, and then get drawn in and start at the beginning of that book. There are many series where I've reread a few books many times, and others much more rarely. I don't think I've ever reread a long series (say, more that four books) from beginning to end continously, no matter where you place the beginning.
