I've noticed "Just sayin." getting used more often at the end of posts on message boards. Think some people like to use it as 'their' trademark/signature line. Also think some people use it to soften whatever has just been said; reminds me of "just kidding" when both parties know the person was serious.

I find it grating and not at all cute, but that is the case with most phrases that get grossly overused in speech and/or on line. There are a few things I'd like to see retired; if just LOL and OMG would go away, that would be great.

Just sayin.
