I am thinking about moving from an occasional contributor to it becoming a major hobby. Reducing the search costs of information is a way to make the world a better place.
I have Masters degrees in Mathematics and in Economics, and work in Finance. However, there are several areas which interest me.
I think one of the best ways to contribute is to look for gaps in articles, and then look around for an online source which legitimises closing the gap.
Please follow the best practice at Revert only when necessary and the Wikipedia Guideline at Please do not bite newcomers. A list of tags, which are often better than reversions, is here. If someone has reverted a good faith edit of yours with no explanation, please let me know. If I can't explain to you why, on the balance of probability, they legitimately did that, that's unacceptable behaviour, and I promise I will revert their reversing your edit. That will look better if I do it than you revert yourself.
