It's not being dismissive. It's great if folks have the critical mass to start a new Wikipedia, and that's why there's been discussion about defining a "starting set" of articles, front page, initial contributors, etc. However, Mark has an exuberance in starting new language Wikipedias, often without any prospect of sustainability.
1) http://scn.wikipedia.org/ - created October 2004, well-maintained by a number of regular contributors with now nearly 300 articles. 2) http://fur.wikipedia.org/ - created 25 January 2005, currently has 5 articles and appears to be doing good rather than bad so far. 3) http://sc.wikipedia.org/ - created a very long time ago, when I was still new to Wikipedia. No regular contributors, 3 articles. The difference between the other two is that for them, support came before creation rather than after.

(of all those other Wikipedias I have supported creating which were eventually created, ang: is doing well, got: is not, and tum: appears to be a bit stale though this had no opposition from anybody)
