Re "I've heard bad things about writing articles on Wikis. Lots of ego-wars." you hear those things from new Wikipedia users who decide that the first thing they should do is either [A] "Fix" the Donald Trump article, [B] try to use Wikipedia to advertise their garage band, or [C] try to correct the biases I list at https://en.wikipedia.org/w/index.php?title=Wikipedia:YWAB
If you pick an article, check the history, and find that it ISN'T getting 300 edits every day, you will have a much easier time improving that article.
My Wikipedia page has a link so you can email me. I will be glad to help if you want to become a Wikipedia editor.
EDIT: Fixed a bad link.
