Customize GitHub Home Page with Markdown

I’m not sure if this has already been suggested anywhere or not, but it would be really nice if we could customize our homepage in GitHub with markdown similar to how we can customize our profile. Like, our profiles can be modified if a “USERNAME/USERNAME” repo exists with a “Readme.md” file in it. It would be nice if the same could be done for “USERNAME/USERNAME” with a “HomePage.md” file. This way when I access GitHub I could have a custom dashboard along with the normal information on the GitHub homepage while logged in.

I realize this is the community forum and not the appropriate place to submit an actual feature request. But I figured I would post here in case the topic is already being discussed somewhere.
