This application aims to show you who your first follower was in twitter. It’s done with PHP and jQuery and of course it uses the twitter API. Two of the available API methods are used : statuses/show and followers/ids. Note that the rate limit is 150 requests per hour (you can increase this) so it might happen that it stops working in some point of time 🙁 For this reason I don’t provide a demo page, but you can download the application, and install it locally or in your web site and give it a try. Anyway, the purpose of this post is just to show you how to do it!
