Regular expressions can be a great help when sifting through a string of information. They provide an excellent alternative to multiple hand-written comparisons. Unfortunately, they are usually tough to read and debug.

There are also a lot of free desktop based tools which not only test but help you build regex's such as Expresso: http://www.ultrapico.com/Expresso.htm

Good list.

The article mostly concentrates on online testers. It is good for flexibility (available everywhere with Internet connection) and portability, but except for the Java applet based one, or those relying on server side testing, it might restrict to JavaScript REs, which are pretty limited.
As tCodex pointed out, there are lot of good desktop testers, like The Regex Coach, PCRE Workbench, etc.
Interesting list, worth expending perhaps. Could also use a bit of editorial work, like specifying the kind of tester (online, desktop for x system), the kind of REs it tests (JS, Java, Ruby, PCRE...) and perhaps even some opinion...
