Python is a good language to learn. Lots of great projects in it and I've seen that a lot of bots are programmed with Python. I'm focusing on #javascript and hope to interface using some of the javascript libraries for Steem.
I will be avoiding Solidity for a while, as I see some limitations with Ethereum and I only have so much time. I'll probably stick with Javascript for quite a while.
Good to connect with other people on this quest!
