To love clojure you'd have to first become proficient in it...

I do not think that the GP was using 'love' in that sense. You can 'geek out' about news and information about something without actually being much involved in that something at all. Witness the popularity of posts about space launches on HN. I doubt that there are very many actual rocket scientists, but we sure do have a lot of people interested in progress made in space.

Love for space travel and love for a programming language are two different things entirely, the one is an adventure on an almost trans human scale the other is a way to tell a computer what to do.
