Markdown is a common formatting system for github, reddit, and a few other sites. I like how it works so have been looking up more complex how to's and messed around with comments on some sites to see which may support markdown formatting. One thing it lets you do is hyperlink sites where [This would be the link itself](and the actual website goes here) like [Google](www.google.com). That doesn't work here, but I gave it a shot as I've been linking that way on Reddit all week when needed. Markdown is neat, but also a buzzword for simple text formatting.
