I've built a couple of Chrome extensions and is something I really recommend. It's easy, useful and satisfying (if you have a userbase).
An example. I love checking the EXIF data of the pictures on the internet to know more about how they were shot. I use Jeffry Friedl's Exif Viewer (http://regex.info/exif.cgi). The process was: right click on the image, open in new tab, click a bookmarklet, new tab opens with the exif. Then, I decided to create a super simple Chrome extension that adds an option to the context menu of all images that opens the image in the exif viewer.
