Pros and cons. Switching away from a mainstream language is hard; you lose the community and all the work going to it. But you gain a lot of technical power, and possibly find a small community of really smart people. Sometimes you can get the best of both worlds by doing something like ClojureScript, which is to compile to a mainstream language. That is compelling. In the end, Lisp is really powerful, it's better than other languages, and it's worth learning. If you can deal with the lack of a huge community, you'll be fine. Clojure is gaining quite a large following, actually, so it's one of the best environments to learn Lisp.
