re: "I only speak english and spanish (with a strong preference for english), and I mostly want to talk about technology-related stuff, programming, news, OSS, linux geekery, etc."

For the Spanish (+GNU+linux+geekery) bit, we've got https://quitter.es @drymer @elbinario etc. etc.

If only Reddit didn't suck so much maybe I could motivate myself to get an account and reply there. Too bad they don't do pingbacks, webmention or salmons...
