Fellow nairalanders why is it hard for Nigerian web designer to design a complex but easy to use sites like Facebook, instagram etc are we being taught the inferior web design skills or are they hiding something from us and I mean the whites

Nobody is hiding anything from us. It's all out there for grabs, free. The question is creativity and dedication.

To create such complex products, you must expand your knowledge from the pages of programming language tutorials to more academic and standard concepts in related fields. Such products have strong integration with many disciplines. That's how broad it can get, and even more.

You need to stop generalizing. There are brilliant Nigerians all around, both in Naija and outside doing amazing things with software.

To design a website is easy. To scale a website is difficult. Programming is not that difficult, to make it work for very large amount of data requires a different skill set. To have a solid grasp of this, you need to be well rounded and have knowledge that goes beyond programming. Core computer science knowledge is mandatory, business and marketing skills are also important. All of these are free online. All you have to do is search. Coursera has lots of programming classes for free, so does EDX. Mit, Harvard and Stanford also have some videos online. So long as you are willing to learn and willing to spend the time, you can build such complex site. Cost of production outside of human capital/time is also very cheap. You don't even need a fancy computer.

So stop making such sweeping negative and self defeating statements, start learning and start building.
