The rise of Github pages made it more polished to display documentation to users. Not only it gives you the full power of html and js , it also works well with doc string documentation systems like Sphinx.
http://www.sphinx-doc.org/en/stable/ Both Squeak and Pharo lack such tools. Personally I prefer Github pages and doc string system. I am not a fan of wiki. They end messy and very badly documented. Especially c2 is quite a mess, probably the worst wiki I have ever seen. In the end however one uses what one find more suitable to the way he or she thinks. But for me having the documentation inside the code instead of separately plus a nice polished github page to display it is the way I prefer to work for my projects. For Pharo, Pillar, plus GitBooks is hard to beat https://www.gitbook.com/book/kilon/ephestos/details
