Whatsapp's read receipts finally work the way you thought they did

Chances are, you've been interpreting Whatsapp wrong this entire time. Most people look at their sent messages, see those double green checkmarks, and assume those missives have been read by their recipients. Not quite! Those only indicate that they've reached the pal in question, but the Facebook subsidiary finally changed those checks to work the way you thought they did. According to a newly updated tidbit in Whatsapp's FAQ, you'll be greeted by a pair of blue checkmarks on your message when the recipient finally gets around to opening it. It's a minor, if terribly useful addition to the mix -- now that that's out of the way, the team might want to spend a little team seeing how it can make the service a bit more secure.
