I guess it depends on the table and how likely you are to get a raiser. I don't like it because it provides a lot of people a chance to limp against you and that's no good. From UTG if he had suddenly found himself in a 5-way limped pot he's screwed.
If you're in later position you can minimize the risk of limping with less people to act and you still might get the raise you're hoping for, but generally I raise a pot when I enter it (with the obvious exceptions of course) and very rarely will I limp if I'm first in.
