I wouldn't worry about it unless it's causing a problem. RAM is there to be used, not horded.
It's down to a combination of things, including your physical and virtual RAM, page caching, your recent visits to sites, and memory leaking. I sometimes hear similar criticism of Phoenix/Firebird/Firefox, which also takes a lot.
