For more information on using Gopher, WWW, and WAIS, read the Usenet newsgroup comp.infosystems.gopher, comp.infosystems.www, or comp.infosystems.wais.
There are plenty of Usenet newsgroups dedicated to postings of software binaries (ready-to-run programs) and source code. These groups are great ways to find the most recent versions of popular programs with a minimum of fuss, but they aren't useful as long-term archives. After the messages expire, the software is gone from the Usenet until the next time it is posted (if there is a next time).
The easiest way to find them is to look for Usenet groups that begin with comp.sources or comp.binaries. For example, the group comp.binaries.mac contains new versions of a variety of shareware programs, in BinHex format.
