I decided to add a del.icio.us badge to the wiki. I use [del.icio.us] to keep track of my bookmarks, and I thought it might be useful to help tag some of the content on the wiki. Initially, I thought about just adding a link, but then I decided it would be cool if you could you could see what tags had been assigned to a page, and if anyone else had bookmarked it.
I first looked at del.icio.us' API, and then I found their badge. Maybe later I'll switch to using the API so the page can load quicker, and cache the del.icio.us information.
I started by taking a look at [tagometer] on del.icio.us' website. Next I wanted to figure out how to add this to MediaWiki. I found a [guide to adding Google AdSense to a MediaWiki]. Since I wanted about the same thing with my del.icio.us badge, I figured this was a good place to start.
