Thanks for mentioning WikiProject LGBT Studies. We could definitely use more good editors on that project. I spoke earlier this year at a meetup at the Wikipedia Foundation about my experiences and frustrations as a queer black trans Wikipedia editor. We also had another Wikipedia meetup recently where people from the San Francisco Public Library showed us how to use their resources to improve articles.
All of your suggestions for contributing to Wikipedia are great, and examples of things I’ve done recently myself. I tend to look up anything and anyone interesting that I see on TV, and see if they have a Wikipedia article. When I saw a great tap dancer, Joey Hollingsworth, on TV and saw he didn’t have an article, I created one. When I saw an amazing pianist on TV, André Watts, and saw his article needed a lot more references, I added some.
Both of the above performers are black, and I’m also always looking to improve coverage of people who are marginalized due to their race, gender identity, and/or sexual orientation. I contribute photos to Wikimedia Commons as well, and focus on representing people of color and the LGBT community in my work.
As a person who suffers from depression to the point that it’s difficult to get out of the house much, let alone do a significant amount of “boots on the ground” activism, editing Wikipedia is indeed a good self-care outlet for me. It’s a place where I can put my writing, editing, and photography talents to good use, from the relative safety of my home.
