I'm done writing my little blog merging program in Java, and as you might see from the current state of this blog, the merging worked. I don't know if it would have been able to do it any faster by hand. But I got a first hand look at the Google API. The API is generic, which is both good and bad. Good because they can apply it to any service that can be viewed as a feed. Bad because it isn't necessarily clear what a particular call really does. You have to familiarize yourself with the underlying data model which is generally based on the Atom standard.
Where to from here? I've spent a few hours writing this program. Should I turn it into a full fledged blog management tool? It will be a really good exercise in learning some UI programming. I've never really invested serious time into that.
Oh, I also discovered how little functionality the Blogger post management console really provides. Ugh.
