I don't personally like them at all. However, a quick google search reveals a "cult" following, tons of websites dedicated to the McRib and figuring out where/when it will be available and even exactly what is in it.
Ok, I know I'm a total geek for this, but a few months ago (maybe even a year ago) I sent McDonalds Corporation an email complaining about the McRib being only a seasonal item and not part of the regular menu. Well, yesterday I got a letter from McDonalds announcing the return of the McRib (still only for a limited time, sadly) and coupons for two free McRib sandwiches. Sometimes being a total geek can pay off...
I'm not all too fond of fast food, though I do like my occasional Subway... and the name "McRib" sounds like some sort of wet spongy material... But that's just me
