It's much better than nothing, although not perfect.
Somehow I knew someone would bring this up.
And I know why you knew it - because it's not obvious how to find it. RSS feeds are usually linked in the page header with <link rel="alternate" type="application/rss+xml" href="..."> so that the browser or feed readers can discover it automatically.
Having neither that nor a link labeled "RSS" or "Feed" or so renders it basically invisible - except for those who had the luck of reading this thread ;-)
