Jo Luijten of Squirrel Monkey is back again with another episode of Wonders Of The World Wide Web, this time talking about the amazing MS-DOS application; WhatsApp. Amazing to see how far Whatsapp have come since the 80s. Imagine having to trawl through your Emoticode Book in order to send a middle finger to your mother! Now you can do it with a few taps of a screen. Simply amazing.
