I've come accross it. I don't actually use Ruby (atm) for web scripting,
so Mongrel's not in my immediate locus of attention :)

What I had in mind was a fun and easy setting for trying to show a few
reasons why I like the language.

:) Not at all.

I am (among other things) a comp sci, and I'm proud of it. Those are
interesting topics, and various approaches would be amenable to doing

If you don't ask, you wont get told?

Wish I new. Personally, I think OO's realisations are flawed. Class
hierarchies seem to model the universe in quite a brittle way, and
tucking state away in objects seems brittle too.

What OO does get right (absolutely spot on, IMHO) is that it's really
useful to have a context (an object) within which you can ask abstracted
questions ("What colour are you?") or make a change ("I change your
state to being an email that is ready to be sent!"). I question the
mechanism that makes that work: classes, inheritance, virtual functions,
multi methods, state stored in frames...

...But I'm at a zero beer level at the moment, so I'm not in the right
mood for a fight about it :)
