Partial Feeds
Most software used to do news transport includes a method of specifying which newsgroups are desired and which are not. This permits "partial feeds" to be set up. Partial feeds are useful for various reasons, among them:
- Decreasing the volume of Usenet carried, which will decrease bandwidth requirements and decrease storage requirements.
Usenet started as short text message teleconferencing. As the popularity and uses of Usenet evolved it became possible (and popular!) to send graphics and other binary data within a message. These newsgroups can be a majority of the storage requirements of Usenet.
alt.binaries groups may make up a majority of the volume of Usenet. Most news administrators treat alt.binaries groups differently, (with shorter expiration delays, for example) for the practical reason of limiting the total storage required to retain them.
- Preventing undesirable content (erotic discussion groups, for example)
- "Filling in" newsgroups that are missing from your other feeds. (A geographically remote site may have better feeds for newsgroups which are desired locally, but not the bandwidth to support a complete feed.)
