Online conversation is riddled with acronyms (LOL, ROFL, BRB and so forth). Here's one I plan to use much more often when confronting the bleeding obvious: NSS.
NSS stands for "No Shit, Sherlock", a phrase which could definitely be employed in many online contexts. Just as long as we don't confuse it with RSS, everything should be fine and dandy.
