Two months ago I abandon Tumblr and decide move to Medium but both options were discarded because some friends talked me about Github Pages and after a short revision (pros and cons), I decided take it great option for continue with my blog in blog.joedayz.pe.
Github Pages is highly customizable and with Jekyll you can have a great blog with minimum effort. You only need a git repository in github, for example joedayz.github.io and create or update locally your contents and do add/commit/push. Nothing more.
I hope that it blog will be useful for you and co-workers, please, share and leave some comments in each article, your opinion is very important.
