GMail RSS Feed Tips

I noticed my GMail RSS feed was not showing new mail in NetNewsWire - so I tried browsing to the feed URL which generated an SSL warning indicating that the certificate belonged to gmail.google.com and I had been trying to use mail.google.com. My guess is that NetNewsWire (and probably lots of other RSS readers) suppress SSL warnings and the connection just fails. By resubscribing with the correct URL - https://gmail.google.com/mail/feed/atom and it works like a charm because this URL works without warnings in a browser.
