Just saw a cool blogpost about summing up all your subscribers on RSS, Facebook and Twitter. The only issue is that it requires PHP to work. I decided to quickly rewrite it as a YQL Execute table instead. So rather than write that code in PHP, here is the code for my table. Pretty simple. You pass it a URL for Feedburner, an id for Facebook and an id for Twitter and it generates some simple HTML for you to display as a widget.
The html page that he uses didn’t have to be changed that much, you can find the same demo that he uses here. This was really quick so right now there is no way to leave out one without it freaking out. This is more a tech demo than it is a real solution.
