Hi Edouard,
The folks at WXForum.net have tended to be a polite and mellow crew for most of our 11 year existence. Yes, there have been outlier responses, but thankfully, few and far between.
The laments about the decline of Wunderground after the IBM/Weather Company acquisition have generated a fair amount of fervor in postings with some folks just saying good-bye to WU. I think that WU is genuinely trying to get their house in order this time, and not just trying services reduction (NOAA radio feeds, Webcams-off-then-back-on).
