1. Novelty. We get bored easily at our jobs, and Lisp is different (but not Haskell different), so we're naturally pulled towards learning about it.

2. Nostalgia. A lot of people here have enjoyed Lisps for years or even decades (myself included) and we have a natural bias towards preferring Lisp-based blogs or articles or projects, partly in the hopes that something is new in the land of Lisp (it never is).

3. Chain effect. When one topic comes up that's very interesting, people often want to know more about that topic or similar topics. People who want more points are eager to submit related links.

4. Propaganda. Some people have bought into a certain Lisp full-scale, and really want to help spread it in the industry. There's even a full-time job title for this called "evangelist".
