My goal: I have a list of names for a friend list. If any user is on it, change their post color.

It appears to work in fiddle, http://jsfiddle.net/j935k/7/

But fails on imgur.I've tried many options. (I do get console.log output, so I know it is loading it. )

some of my attempts:

only shows the first user, It should create a list of every div.author's first-a-child.

$("div.author a:first").each(function() {
    var x = $(this).text();    
    if( nameInFavs(x)) {
            $(this).css("color", "orange");
    }
});

This matches nothing.

The urls are always in the format of

    <a href="/user/foo">foo</a>

so I tried to partial match, or prefix-match without luck. a[href~='/user']

I've written userscripts on other webpages, What am I doing wrong? Is there something special happeneing at imgur?

Code from jsfiddle:

var favs = new Array("foo", "bar");

function nameInFavs(n) {
    if(favs.indexOf(n) != -1)
        return true;
    return false;
}

$("div.author a").each(function(i) {
    console.log("i= "   i);
    var x = $(this).text();

    if( nameInFavs(x)) {
        $(this).css("color","orange");
    }
});
