Several software applications provide feedback forms in case of an error or crash (Windows, Firefox, etc.). Today I was browsing a blog that had an embedded VideoEgg player and it popped up a unique error report, requesting help and offering a free t-shirt for helping them track down the problem:
I like this approach. It’s very hard for developers of free consumer applications to track down and solve reported “crash” problems in the field. At Palm we had a couple cases where we contacted individual users and did remote troubleshooting with them. I think we sent them some free Palm schwag for their help.
