Quick hack: making Journalist slightly more responsive

I’ve been using the Journalist WordPress theme ever since I migrated to my self-hosted wordpress.org instance, away from wordpress.com back in 2007. The Journalist is a pretty basic theme, 2 columns and fixed width. The last version on wordpress.org dates from mid 2008, but the developer did work on support for threaded comments and sent me a beta-version (1.9.1) in January 2009 which I currently use. A couple of months later, after having been stalked by yours truly for info on further development, Lucian replied he was busy with other projects and that he could not do too much “free” work any more (which is completely understandable). Ever since, I’ve been making small changes left and right, fixing minor bugs and making small improvements.
But the problem with fixed width themes such as Journalist; they’re not responsive. Although responsive design is great and all, I didn’t really bother with it until I needed some responsiveness to be able to test upcoming changes to my own WordPress plugin. And that’s why I added the following in /wp-content/themes/journalist/style.css:

@media only screen and (max-width: 880px), only screen and (max-device-width: 880px) {
  #container, #content { width: 98%; }
  #sidebar { display: none; }
  #bubble { background: none; height: 32px; margin-top: -24px; position: static; }
  #bubble p { background: none; color: #000000; font-size: 14px; }
}

This is just a quick hack, making the main content div variable in width, hiding the sidebar and moving the tagline from the bubble on the right to the left, underneath the site title for all screens with a width of 880px or less.
Feel free to use and to provide improvements in the comments or via the contact-form! And Lucian, if you happen to read this: any chance anyone could resume work on the Journalist?
