If it's easy to understand then I guess you can answer my questions?

I don't think "go write your own" is a legitimate response to my questions (if that's ever a legitimate response).

I'm using websec as an existing tool to watch website changes. It's not perfect but it's good enough.

For a while I had a webapp to do a better job but it never got any traction, most likely because I had no idea how to get traction. It's an interesting exercise to write such a tool though.
