Show HN: Add the Missing “My Posts” & “My Comments” Links on Top of HN Website

This really doesn't require a heavy jQuery dependency. I also don't know why the font related style changes are necessary.

You could rewrite this script to be as simple as:

    const me = document.querySelector("a#me").innerText;
    const header = document.querySelector("span.pagetop");
    header.innerHTML = header.innerHTML + "<a class='myaddons' href='https://news.ycombinator.com/submitted?id=" + me + "'>| my posts |</a>";
    header.innerHTML = header.innerHTML + "<a class='myaddons' href='https://news.ycombinator.com/threads?id=" + me +  "'> my cmts |</a>";

Much more efficient and does the job without the heavy jQuery dependency.

I do commend your initiative though, and I'm sure many users will get much use of this.
