RSS is a language to deliver content to news readers, not a browser (unless, of course, your browser doubles as a newsreader, as does Firefox and Safari). WordPress already has RSS automatically built in, so you do not need to do anything but Post up content. So, RSS is a support to your blog, and delivers content to users, but not in the way I believe you're assuming.
To post up content, just design your theme using the wordpress theme/tag designs as intended. Use the admin to post up articles and write pages - RSS feeds will create themselves automatically, and depending on your design, the admin system you're using to write content will post to your site accordingly.
