Most of our local stations have disappeared from the Blunder(Wunder)Map, so I've removed the BlunderMap link from my menu system. It appears that only the last 150 or so stations numbered from KLNKNE100 or so on up are on their BlunderMap.
They still receive my station's data, but the only links to WU on my site are to my station.
BTW, their FAQ lists the possible reasons for stations disappearing from the BlunderMap, and longevity isn't one of them. They leave us with the impression that it's a QC issue, which is laughable. After all, local variability, aka 'microclimate', is one of the foremost reasons we have our own weather systems.
