If you are guessing that all engineers who understand how to use the command line are well-organized, I can provide you at least one certified example of one who doesn't match your worldview. This is awesome.

I can certainly see where you're coming from. Many of those people would probably benefit from Hazel more than Maid, however. :) As it stands, Maid is somewhere in between hand-crafted shell scripts and a user-friendly GUI (but definitely closer to the former).

That said, Maid has certainly helped me out, and I'm happy that so many others have found it intriguing. (Thanks for the comments!)

I don't see why computer skills and meticulous organizing would be correlated. I usually see the opposite, in fact.
