AtomAPI Problems and the Road to Beta 2

Sorry about the radio silence the past week or so. It's been really hectic around here. Several of my friends graduated from college the past 2 weeks, so my weekends have been full of partying ;). But I've been working on VisualBlogger 2004 very heavily, walking down the long road to Beta 2. I've made a ton of progress, and the client is much more stable now. We have a complete implementation of the Provider Model, a la .NET 2.0, which I am extremely excited about.

So where am I at right now? Well, I'd like to do a bit more cleanup work on the individual providers before I release Beta 2. There is some functionality that I took out in the transition from interface-based providers to base class-based providers. It really should get back in there before I put it out.

I wanted to have an AtomAPI provider for this launch too, but I'm having trouble testing it against my Blogger.com account at http://atomapitest.blogspot.com. I keep getting a SOAP error "You must provide a BlogID". So far I haven't had any responses from my request for help. So I'm left with 3 questions:

1. Does anyone know how to get around this problem?
2. Does anyone have another AtomAPI endpoint that I can test against? http://www.blogger.com/atom isn't cutting it for me.
3. Should I wait until I have AtomAPI working before I release Beta 2, or should I release the provider separately when it's done?

Oh, it might be important to know before answering those questions that we currently have a basic implementation of the MetaWeblogAPI, so you can post to any blog that supports it. I'll be improving the functionality for the final release, but right now it basically does everything the other providers do.

Any help would be appreciated. I spent most of the day stuck on this stupid thing, and I need to get moving again.
