Community Building & Writing Skills
Writing is one of the most important parts of a community. Whether it is at the building aspect, where guidelines and content has to be created by an organisation. Or whether it is at the user's end, where we as users write content and read content that's written by others. Grammar, ease of communication and how interesting the topic is. Knowing all of this is key to a good article.
Let me know whether you agree or not. Will motivate me to write more often. I have a lot of free time anyway :)
