I'd like to add my experience to the previous posts.
About one month ago, I tried MacReporter and liked it very much.
I sent an e-mail to the developer with a few suggestions for future versions of the application.
Well... I did not expect that he would rush to include them in MacReporter. (Of course not.) However, I expected some kind of feedback, to show that he cares about what users think of his software.
Until today I got no reply at all!
If he had dropped me one or two simple lines, I would have bought a user licence for MacReporter the very next minute.
With this "Who cares!" attitude, he just lost a customer.
