Andre,

>It seems to me that the wiki is a better place to hash this out than in threads. I'm surprised this topic hasn't been initiated there

Wiki is good for long-term ongoing discussions if you can think slowly enough to keep up with the speed of the discussion.

Here, you may have 100 messages in a day on an interesting topic. Where the wiki shines in discussions, I believe, is in refactoring and distilling the discussion into a more concise representation of the topic when the discussion finally trails off, or even as it is still in progress.
