I've seen a lot of people talk about #markdown for taking notes and various other things, which is definitely neat - more open data is a good thing - but the topic of different dialects of MD (flavors) doesn't come up as often as it should IMO. That lack of consistency threatens one of the big draws of plaintext data: Your data is consistently formatted, and a computer can leverage that to automate things. And sure, org-mode exists as an alternative to MD. But then you're dealing with emacs xD
