[AMRadio] What is the purpose of these replies?

[D. Chester]

This has had me puzzled for a long time.

I have noticed that very frequently someone will reply to a previous message 
on a thread by simply quoting the entire message and adding nothing new, no 
comments or anything.  Just the original text with ">" at the beginning of 
every line.  No follow-up or explanation.  What is the purpose of this?  Or 
did someone just click on the wrong button?

I get enough junk in the inbox with replies that quote the every single 
message in the entire thread, headers and all, along with the new message. 
But when there isn't even a new message it really baffles me.
