One of the best things you can do is make sure people know about it. I recently (< 1yr) started at a small company which does a lot of text manipulation, because our product is data. Perl is a natural in an environment like that, but no one here knew it, so I offered to give a one hour "intro to Perl" talk. I covered the basics, gave simple examples, and showed people where to go for more.

After five work days, I'd had four people (out of the 25 at the talk) asking me to help with scripts they were writing. So it looks like that little bit was all the spark that was needed here. (YMMV.)
