The guys and gals who make NOTAMS should be tasked with reading all the NOTAMS within 4 minutes (all we are allowed) and if they fail, they should be put out to grass.
Just to show what we are talking about here is an actual volcanic ash advisory from pilot departure documents:

You can actually figure out what it says if you guess a little - e.g. PSN must be positon since it is followed by a lat long but why are we still using decoder rings in this era of high speed internet and laser printers? A few more vowels, a little punctuation, graphics and some formatting sure would make this easier to read. I realize there are much better versions of this advisory available on web pages but often the terse teletype text is all that makes it to our paperwork. Of course, if something goes wrong, they'll have the full color graphics at the hearing.

Apologies for talking a little shop with this operational pilot stuff on the ash advisories.
