Here’s quick patch I made to my Typo 4.0 installation to add Reddit and del.icio.us buttons to articles. Now one click is all it takes to submit an article to either site. (These buttons appear on my blog at the end of each article.)

If you want to apply the patch, be sure to also place copies of the button images into public/images. You can snag the images from my site or from the Reddit and del.icio.us sites.

Here’s the patch:

The code is begging for a little refactoring love, but I’m off for vacation in about twenty minutes, so it will have to wait.
