Tags don't match articles I want

Just unsubscribed from weekly emails. Thought I'd point out why. I want to see articles about, for example, the Go programming language. (Or Dart or whatever.) But Golang gives zero results and the top three on the list for "Go" this week are:

• Go live with a friend on Instagram
• Become the Master, or Go Away
• Go Large with iOS 11

These are clearly not what I was hoping for. Without better tags or some sort of context the service becomes more spam than useful. At least as it appears in my inbox each week.
