No, I can tell you from experience. Even with a palate accustomed to cheap beer, Billy Beer was still lousy swill. I can't imagine it's improved with age...
That said, I've probably eaten some MRE components that were over a decade old, along with canned food that was much older than I'd want to think about and it was still fine. There's a story of a shed in Antartica full of canned crackers from one of the expeditions around the turn of the last century (Scott, I think) and they're still edible.
Mike - the article applies to dairy products, meat, cereals, and lots of other foods that aren't packed with a ton of preservatives. Also, canned foods can last for years (avoid if the can is starting to buldge out). The point of this post is to encourage folks to use some judgement and trust your nose rather than going strictly by the date on the packaging.
