I'm a year and change into my job at metabase (metabase.com) writing clojure all day every day and I am still terribly surprised that basically it is all that it's promised to be.

That said, you do need to actually use the repl and be repling all the time because the startup times suck and the stack traces are gigantic all the time. That's pretty much it for complaints. You would expect things that aren't apparent in 30 minutes looking at the language to come up after an entire year, but nothing so far.
