If phone lines are considered online, then yes. I learned mostly from listening to conversations. The easiest is just to listen.

If you cannot be around native speakers, try phone calls. Making a phone call stops you from feeling ashamed, but helps you to practice (standard) sentences and listening. It helps that they usually have a specific context. Look up standard sentences for a topic (like hotels or restaurants) and just call. If the call gets awkward you can always hang up.

People on HN seem to be more open minded and curious. Reddit seems more judgemental. Just my 2 cents
