From website to mobile apps, everywhere social media is being used for collaboration, sharing, and information discovery. We have listed some of the tools here which are ideal helpers for both advanced app builders or those just starting out with HTML or PHP.
Stack Overflow: Whether you have a programming error or a general question about development, this is the community-based place where you get all the answers.
GitHub: One of the useful tools for collaborative and social software development. If you are building a product, GitHub's development news feeds, secure repositories, and inline editing are invaluable.
EtherPad: A robust collaborative code editor with a free version and several paid ones. It's easy to share code and work together to build the best application possible.
W3Schools: Though it's not truly social media, yet the better place to learn almost any language for free. It not only has great tutorials but has a wealth of tools to help you understand how the code works and an active community on its forums.
