Brian,
Thanks for the civil comments.
I think that language diversity valuable, and there is no requirement to post in English to this list.
Although I appreciate the idea, I am unwilling to create a more narrowly focused version of these threads for Wikitech-l. Someone else might be willing to do that.
The 2 !votes against and 0 !votes in favor of continuing to cross post these threads to Wikitech-l in their current form likely mean that I will post these threads only to Wikimedia-l in the future. Although I am mildly disappointed, I am OK with that.
