@JohnsonDDG ,
There are plenty of goods to discussing current events, it makes you a better citizen, and in my case, it's largely how I learned to speak English properly.
That said I do feel like a failure when I engage in the political discussions here. They're typically not conducted at a high level, due to the low number of posters, as well as some posters not knowing very much. It's not a great investment of time.
I should be reading and occasionally commenting at more elite communities, where I'm being challenged. I've interacted with people online, whereby nearly everytime I argue with them I find myself humbled quickly. They're sharp enough to make me change my mind on things, due to their knowledge, their ability to reason and communicate. Those are the people I should read.
A notable exception here are the posters who tell me about life in Europe or the Middle East, I do learn something there.
