Javascript, Links as "objects"?

I am designing a site for my friend and he wants a pseudo blog thing that's "better than a blog but isn't itself a blog". So I have a right hand column with all the articles he's written, but that would appear in every page. Is it possible to make a javascript application that "loads" the links onto that page, so my friend will only need to add links to a "remote" javascript?

That is to say, I would like to make an array of links that my friend can add on to; is this possible?

I would think it is. Just have a function that outputs the links, and save it as a .js. use a script tag with src=your.js and update the js file whenever you need to. Or did I misunderstand you?

No, that's actually a better idea than mine. Just use document.write("<a href="source">LINK</a><br><br>"); right?
