The document discusses various models of support for open source software (FOSS), including paid support options as well as community-based support. It outlines different types of community support like mailing lists, forums, and IRC channels. The key benefits of community support are its low cost and ability to provide quick answers from a diverse set of users. However, community support can be unpredictable in terms of response times and whether issues get resolved. The document encourages becoming involved in FOSS communities by contributing answers and code in order to receive more support in return.
