WPRS was coded from scratch, uses its own database, it is not a modification of any plugin. Nor does it come with someone else's affiliate script, it's just the same features others charge $67 for, again written from scratch (WP Affiliate or something).
I don't mind competition... there have always been 3 or 4 other plugins that try to add ratings to WP. Problem is they all suck. They're rent-a-coder quality like you'll probably get, which means they don't use the WordPress APIs correctly, try to hack things intsead of using filters and hooks, making them harder to install, harder to debug, and likely to break when WordPress upgrades. And most of them were released once in 2006 or 2007 then never upgraded, while WP 2.x is way different than 1.x for plugins.
I have a bachelors degree in computer science, worked for Microsoft and DuPont as a software engineer for a while, in grad school now working on the masters in CS. In other words, I'm a real programmer, not some kid who hacked something together. For the customers this plugin has gotten already, I've written pages of code by e-mail helping them create custom sites with it, because I have worked with WP for years and have ripped it inside out enough to know how to make it do what I want in an upgrade-safe way.
Typical programmer: It's impossible for anyone but me...
But the real question is: Do you forgive me for fucking your mother?
And your background don't impress me. My 'other' team has guys who went through Kennedy school of whatever at Harvard, MIT, and IIT and have 20+ years progressive experience. Most of these guys have a net worth you and I combined couldn't touch. You are likely very good at WP, but so are 50,000 other guys.
