What do you Monks suggest to a person trying to keep their skills "sharp" and improve?
Read, Write, Repeat. Read just enough to have a partial idea of how to do something, then make use of that knowledge and write a program that does something interesting/useful. If you read too much without applying what you've read, you won't find it nearly as interesting and you'll forget it far faster.
Where can I look to for inspiration, ideas or just uses for Perl?
If you looking for inspiration Where the inspiration comes from ? has lots of good suggestions. :)
