@Prateekshit73 thank you for the pull request. We are still in the process of determining how to accept new content like this. Our next meeting is mid Feb so it will be a few more weeks before we can let you know of any updates.

none of the content in this section has anything to do with the Pacman rule. While a number of these things are reasonable, the header should be changed

We shouldn't be promoting Twitter, which doesn't exist anymore. We should use the generic "social media" instead.
