As an example, I've been tempted to do some web work in Scheme and Smalltalk, just because the languages are so damn cool. The problem is, I'd be practically alone. And that's just not a good idea. That's the wisdom I was trying to pass on to you: don't look for technology, look for community. Community is the important thing.

Scheme and Lisp have extensive applications in the AI fields, you wouldn't be "practically alone" at all. Smalltalk also has a huge following among OO purists and isn't really "niche" either. Ruby is more niche than Smalltalk or Scheme.

Whether or not you think I need "wisdom" -- so do you -- Don't give up and don't be defeated so easily. You won't ever innovate if you are always a follower and are waiting for someone to go before you. Also, what is the life value in something if it is not "hard" ?
