You could submit your site to an RSS directory
If you want to get more people using your RSS feed, you should submit it to an Rss directory so that it can be listed along side other feeds on the RSS directory that are related to similar topics as your site. To find an RSS directory that is a good place to post your site, you can confer with someone you know that's interested in RSS related topics, or you can search around on line; just head to your home computer, open up a search engine site that you prefer to use on your favorite web browsing application, and punch in some search terms related to the kind of RSS directory that you would like to find for your site, and, I bet that, in next to no time at all, you have access to all kinds of info to help you pick the RSS directory for you.
