Two concerns people who don't use RSS have about using RSS are that people will stop visiting their site and that RSS feeds won't convey the context of the information it's compliing. BusinessLogs addresses this issue in Fear of RSS:

In the worst case scenario when using RSS a reader will never again visit your site. Since I am unable to track usage patterns for all RSS readers I don't know how often this happens, but I can tell you from the statistics from my sites (including this one) the number of visitors goes up monthly even with full content RSS feeds. And even if they do not visit your site again, at least they are still reading your content. This increases the odds that they will link to you from their site or spread the word about your site.
