Since long I am a fan of languages that aren't bloatware.
By that I mean they have a (very) small footprint on disk and often installing isn't even necessary.
In my quest I encountered a few:
   - newLISP (in the past I dabbled a bit in it - no serious work)
   - Rebol (used that a lot)
   - Red ( red-lang.org ) a very promising descendant of Rebol
   - 8th ( 8th-dev.com ) a descendant of Forth (currently studying 8th)
A few days ago I was in need of a small utility and wanted to build it fast.
I chose newLISP and I was amazed by how easy I could pick up all necessary bits and pieces
from the docs and in almost no time I had my utility running.
I have to say that I used other Lisp dialects like Common Lisp, Clojure and Scheme. All these were far more difficult (at least for me) to build a featureful program in a short time.
So I wish to send kudos to the developer!  I hope this language as well as the others mentioned above will prosper.
