Long, long time ago, I started writing my stock trading robots in Python and I am still using it to this day... Not sure why I chose it, maybe it was easy to learn for a non developer like me (one thing I don't like is the syntax), but way too late to change the language, there is no way I am rewriting my robots... if something works, don't touch it :-)
I wrote a script that runs a cronjob that checks if someone posted "What you have automated with Python".
If my bot is positive, it creates a post that says that we had this already a few months ago.
