I would second that. At the risk of hyperbole, the "mini-lisp revolution" could be one of the more important things to happen to the state of the art. Lisps just have so much going for them, but common lisp can not be the answer. No idea about arc, but at least there is some potential for leadership to be shown. People need to just start using stuff for "hobby" projects. Its possible that lisp could become very popular, due to "language oriented programming" - which is just a silly name to attract people (notice how "DSLs" are now so popular, well lisp is nothing if not a platform for creating a DSL which solves your problem for you). heh, its not anything knew, I think words to that effect are mentioned in the SICP notes.
