Well written, easy to understand and I love your humour. Opportune article, too. We're experiencing a heatwave at present, so in the late afternoon, when no direct sun is hitting our palms, I've been giving them a good, overhead soaking, believing, as you pointed out in the article, that it would replicate being rained on and increase the humidity. I've only done this the last couple of days and, armed with the knowledge of the potential adverse reactions, won't do it again.
I think in times of heat and drought, overhead watering of palms is much less likely to result in something bad going on... palms do seem to like their 'heads washed'. But when it is cold (which it is here 1/4 of the year) this practice can be bad for many species (but not all). Some palms resist bud rot no matter how much you soak their crowns (Chamaedorea, for example, rarely rot if you pour cold tap water on them even in the middle of a severe cold snap).
