Since Justin and I have started doing Front-end end Fridays (a weekly look at the performance of a particular web site: keep an eye on the CTFEDs Twitter account for details), I’ve been more concerned about how serious we Front-end developers are about the size and speed of our sites.
I’m a big believer in designing and developing Mobile First. It especially makes sense in South Africa, where many users are Mobile Only. That means that every decision we make should be guided by the harsh constraints that implies. Here’s a short round up of some stats that have been on my radar recently.
Access to phones and the internet
- 85% of South Africans have access to a cellphone.
- About 50% of South Africans have access to the Internet. 50% of those connect using only mobile devices. Most of the rest connect at work or at their place of study; less than 1% connect using only a landline.
