I like answering questions on Stack Overflow. It helps me stay aware of what people are struggling with in a particular language or framework. To do this well, I manage my tags. Here's a screenshot of some of the tags I'm watching (subjects I care about and can contribute answers to) and ignoring (the rest).
With these settings, my question feed is mostly signal rather than noise.
If you visit Stack Overflow often and haven't signed up for an account, I recommend it.Tweet
