LOL--I can attest to that. My favorites are the thermometers sitting in direct Florida sunlight recording 104+º, when two thermometers on my porch show 85º. I appreciate Wunderground for everything but their use of personal wx stations appearing as official local readings.
I'm a fan of them... been using the site since it first started. It's one of the few out there that is continually adding cool new things. I would probably agree that they shouldn't show personal data up in the same area they show ASOS/AWOS data as it is not nearly as reliable or accurate.
