No licking the fibrous blue rocks... check. 

Well, Scott, way down at the very end of that very informative article from Mindat is a picture of "Anthophyllite". I've never heard of it before but I bet we've seen it before in a hole around here somewhere.
Not to mention "Cummingtonite". (Okay, I'll mention it.)

Reading that article and realizing that almost every amphibole also has a fibrous, asbestiform habit, or formation was like a light bulb turning on! It sure makes it easier to understand and process all the different mineral names.
