On my continuing quest to learn how to code I've created a fun little application that lets you vote and rank the current Trends from Twitter. The application is called TrendMeme. In addition to voting, you can see what's currently being said about a Trend, comment on a Trend and even search and browse for past Trends.
Furthering my PHP abilities I used the CakePHP framework to construct this app. I learned a lot about the MVC process. CakePHP has its oddities (the SUM function is largely absent) but overall I think it's a solid tool and it was very helpful.
