Mashing up bits and pieces to build a feed aggregator and reader.
Why? Because Google reader is going away.
No I don't think this will be a replacement. I do plan to finish it to the point where it can be used by me to read feeds.
And then? This is an interesting problem space. Something big will happen in this space. I find that working on code related to a problem space makes me thing about details that would never occur to me otherwise. There are a lot of ideas that will be fun to explore and having this code will give me a place to tinker.
