I personally drink most of mine at room temperature (old house c. 12C)..
Unless it's a Weiss or a Lager... then I'd chill it. If it's an ale, stout etc I think it's a good measure of the quality of the beer... for instance I challenge anyone to drink a Budweiser at 12 degrees.... ughggh... Even chilled to below functioning of tastebuds and it's still disgusting..
