Here's a story along these lines from my student pilot days. I was at an uncontrolled airport doing some night time touch-and-gos in a 152. I was on downwind, and I heard an incoming aircraft, "Waterski 1234" announce that they were inbound and were maybe 10 miles away doing a straight in landing. I had no idea what "Waterski" was, I thought it was some type of seaplane or something. So with him being 10 miles away, I figured I had plenty of time to go another touch-n-go before they got there. Seaplanes are slow, right? So I turned base, and then final, when my whole airplane lit up from the landing light which the guy behind me had just turned on. It was about then that I figured out that this other airplane was huge, and fast, and about to run over me on final. I went around and got the heck out of his way. I learned later that "Waterski" is the callsign for TransStates airlines.
Moral of the story: Airline pilots (and others) please announce what type of aircraft you are when approaching a non-towered field! The little guy in the 152 may not have any idea what to look for or how fast you're approaching if you only use the callsign.
I'll also note that most of the airliners I've heard over the years do, in fact, state their type aircraft in a situation like this. I don't think it is an epidemic.
