Recently I accidently caused a bug in an old, forgotten area of the product that was one of the first things I wrote for Jot. I don't really work on that area any more, because we didn't think it was very popular and so I moved on to focusing on higher impact parts of the product.

Imagine my delight to hear that customers are actually complaining about the bug I introduced! That means that they're actually using it! My heart sings with each angry support ticket!
