I use it for ETL processing as well (*wink,wink*). Basically it's batch file processing, N number of files come into a system, we processes them performing any filtering/transformations/etc, and then load the resulting record set into a database. I work constantly in *nix land, so perl also comes out in my bag of command line tricks, which prior to Perl, was heavily awk and sed.
I've used Perl in the past to manage web applications, CGI and plain ol' dynamic web sites. I use it in maintenance mode now, since I run an installation of Bugzilla at our office.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
