It sounds a bit rude, doesn't it. :)
I'm only a newbie but I think if you write something on here you "blurt it". It's a bit like tweeting on Twitter.
I just "blurted" something. Is that the same as "liking" something?
I would think Blurting is to say something out. When you give someone a thumbs up and thank them, this is what they do on questions here lol.
