After the AI Winter they where of course still both used, but its absolutly clear that they did not have the addoption other languages had.

At no point was it among the couple of most common used languages at least in the last 30 years. Look at jobs, popularity or any ranking for as we long as we have data.

That sounds different like 'no adoption'. Based on that I would say Clojure has very little adoption. Probably there are a few hundred people using Clojure - not more. The latest State of Clojure survey had just 1000 people taking part. Half of those say they use Clojure at work - where work can be anything from academic to industry.

Clojure has to show a few websites, very few applications and a bunch of hobby projects.

Given that Clojure is at a different point in the hype cycle than Scheme or CL, it does not look like mass scale adoption rivalling Python, Ruby, C++, Objective C or Java is coming soon...

In this light there is absolutely no reason to make snide remarks about CL or Scheme 'industry' adoption, where for example Google uses CL, Sony uses Scheme for game programming, where companies use Siscog's scheduling applications, PTC sells CAD systems, Amdocs uses Allegro Cl in Telco applications, various spae and earth telescopes use a CL-based scheduling engine, various companies use ACL2, NASA has a theorem prover in Lisp, ...

If these apps were written in Clojure we would see large amounts of blog posts, ...

There is an opinion that AI Winter was caused by dramatic spending cuts, which quickly results in "brain power shortage", and has nothing to do with The Common Lisp, which is considered as [modest] success.)
