The statement "Not that you asked my opinion, but $23/year for screendimming software--its no wonder people crack this." does not make any sense. If this is an application that only dimms the screen (which you can do multiple ways without any application) why would anyone make an effort of creating and distributing it and why would anyone make an effort on searching for a cracked version of given application? Surely there is some added value to it.

Also "if you can detect that someone is cracking your software or doesn't have a valid license, put a donation link in the shape of a coffee cup in the corner of your software. At least people have the option to support you." I have no data to back this up, but I really doubt that the people that are money-limited or just don't want to pay 20$ for an application will suddenly support a developer voluntarily.
