I'm not sure I'd call what Ruby is doing an 'explosion' just yet. Lest
we forget, Ruby has been on the scene for a decade now, and while it's
growth in recent years has been quite extraordinary due to the killer
app Rails, there are still a number of stumbling blocks for more
widespread acceptance of Ruby as a platform for application
development.

Personally I love Ruby, and I want to see it continue to flourish.
However, I hate for the hype machine to get geared up and attract a
lot of people who later leave because Ruby wasn't quite what it was
advertised to be.
