(Superseded by Interarchy for Classic Mac OS and the command line in Mac OS X.) Peter Lewis' "Finger" is a reliable, simple finger client that also allows you to query whois servers. The most invaluable quick way to check your email (so long as your ISP uses a system that supports finger).
"Peter Lewis strikes again. Simple, easy to use and solid. Can create a list of frequent people you, uh, finger."

Also, if you have an older Mac, be sure to check out the "Classic" applications page for more options.
Finally, take a look at ALEMIA if you think you know that name of an application, but aren't quite sure.
No, I don't accept reviews anymore for these older applications. With the creation of this page in the Orchard's late 2005 redesign, I only accept reviews for currently-developed applications that work on Mac OS X (or later....whatever that might be!!).
