If you do, are yours working for this site? I can't seem to get mine to update.

I do, but I had no idea there were feeds for this site. Are they for separate forums for something?

feed://bikeforums.net/external.php?type=RSS2&forumids=178

SSFG

There is a link to each subforum in the relevant pages.

Google reader works just fine for me.

rss feeds is for n00bs

How about, who is using them with Firefox?

they work fine with Firefox, just make sure you have the latest version 2.0.0.0.12
on the bike forums site just click on the little orange RSS link near the title of the NG
Fire fox will put the links in your bookmarks
