Sorry, everyone, it was a bug I introduced. I wrote some code that looked at the ratio between two hash table entries, and I forgot to specify that I wanted the first hash table reference to return 0 rather than nil if it was empty.
I love that you still have such a close relationship with the code behind HN despite probably being incredibly busy with other things. If my business ever takes off and I happen to remain in an executive position, I hope to be able to set aside time to do the same.
