Personal Wikipedia Edits
Wikipedia is a great (and fun!) place to add specific knowledge and reach a broad audience.
A good time pattern I've noticed and used for editing Wikipedia articles is:
(1) Identify an article that may interest you
(2) See an area that can be improved/added upon
(3) Read and review some recent published research papers
(4) Present a concise summary tying the research paper and article together
Here is a list of some wikipedia edits I've made.
