I agree that reading is important and I suppose that the idea is: The more you read the more you know therefore, you are a valuable member as you can assist others more easily. Which is true but as Tristan said above, reading lots does not always equate to being helpful etc in the community.
But its not always fair[1]. For example earlier this year I was TL3. I went away for a while and I dropped down a TL as I didn’t read as much. My knowledge of Discourse is still there and I was still posting in support etc. albeit not so often. It doesn’t bother me as such anyway I just logged in one day and was like “Oh? where’d #lounge go 
”
Probably the wrong word to use? ↩︎
