PHP Is The New PowerPoint
Playing around with Ning's social application templates recently. Have found throwing together simple demonstrations with them to be so much more instructive and persuasive than traditional presentations. Once you clone one of their templates to create a starting point for your efforts, it's easy to customize them, by simply editing/ extending the source code. Nice for wannabes like me, I simply edit around the edges rather than starting from scratch (which has its own merits under different circumstances).
