Same logic applies to clojure. I think that's the point he's making. Everyone and their 12 year old nephew rockstar developer has questions about java. I also find that clojure questions nowadays are mainly asked in the clojurians slack organization. Immediate feedback is more attractive than waiting around hoping for an answer in stackoverflow.
With any chat interface, it feels like your question may be lost if it's not immediately answered and it's often hard to follow discussions with multiple people chatting. With SO I will spend time to try and formulate a clear question. In general with slack or any other chat I may feel out the room first as it will be a waste of my time writing a detailed question if no one is around to answer.
Perhaps some sort of SO integration into Slack would be the best of both worlds?
Most people looking for help on the internet are searching:
"How do I do X in shell?"
No of people looking for help with the word 'Bash' are likely to be lower.
That's one reason why TIOBE is sometimes way off the real trends.

This is false.

Apache Groovy fluctuates on TIOBE a lot. Six months ago it was at the same 50-ish position as Clojure, which is its usual ranking. It's shot up only in the past 6 months, which has also happened a lot in the past and is always followed by a sudden fall -- perhaps someone's gaming the search engine rankings. On Redmonk, Groovy and Clojure have ranked equal-ish for a long time. In the CloudFoundry report, Groovy is at the same very low rank as Others which would include Clojure if present.
So Groovy and Clojure are at the same ranking in all rankings I've looked at.
