I am using Whatsapp in last 4 years in my mobile.No doubt to tell that Whatsapp is the best social networking site.and it is very user friendly.Service of whatsapp is very good.We can connet my friend easily.and shared many important file, image and many thing through whatsapp.Web version of Whatspp as not good as mobile version.
I m using Windows 7 in my Computer.When I connect the web version of Whatsapp it shows the QR Code which I scan with my mobile version of whatspp.And its easily connected.It is the great thing that I m using Whatspp both mobile and Web.
the negative point is when I connect Whatspp to web.mobile version of whatsapp is must to connect too.if Whatspp is disconnected to mobile it also disconnected to pc.And again scan the QR Code.its Very irritating for me.and waste of time too.
Web version of whatspp is good but not best.
