Using Github Profile Readme as 'Twitter-like' Feed

I had this weird idea of using GitHub profile README as Twitter-like(well, Mastodon TBH) feed! There was no specific reason for doing so. I roughly thought it would boost my Mastodon profile(which is quite new at the moment) reach. Another reason was to see how far I could go with limited tools (as Github ReadMe does not support JavaScript yet). Generating those Cards There was only one thing to figure out.
