When you are just a guy trying to hack something together in your free time, you are quickly and constantly reminded to not reinvent the wheel. That, along with my complete lack of programming skills, forces me to brute force and re-purpose stuff wherever possible (see last 5 posts or so for proof).
The great thing about that, is it helps open my eyes to features/products out there they will perfectly handle the use case I'm looking to implement. The newest ephiphany is that Twitter's "favorite" feature is ideal for creating a playlist of favorite songs that you may hear on @friendP3 or any other "twitter radio" station (current or future).

(by the way, I *love* Jing's screencasting app but they fact that the videos aren't resizable is a major problem since they are all too big - dimensionally - to fit into my blog)
