Getting WEBrick to serve HTML is only about umpty times easier to get
Apache to serve Ruby. Of the reasons mentioned before, the Ruby
integration is by far the most valuable. WEBrick is mostly a development
server, not a production server - you don't need "full-featured", you
don't need fast, nor a lot of other things. The advantage is that it
makes it *trivially* easy to launch said webserver from Ruby code, and
that it's trivially easy to run arbitrary Ruby code as part of operation
of the webserver.

You'll find that in fact, languages used for web programming -very-
often have webservers written in those precisely for the ease of
integration - Java has way too many servlet containers to mention (all
of which implement HTTP), Python has CherryPy (first one to come to
mind), Perl also probably has tons of those. They tend to make showing
results of code in the respective language just so much more
instantaneous that their existence is justified.
