Why would you post a link to your blog promoting the fact that you're thinking about writing an OS? That's like me posting a link to my blog promoting a startup I haven't thought of the idea for yet.
I've been tinkering with operating system programming for a few years now (yikes, has it really been 5?) in my spare time. It's an interesting hobby, and I actually got a job partly because of it. :)<p>I'm interested in hearing more about this project of yours, and possibly contributing to it.
For anyone interested in OSes, I recommend the EROS, Sun Spring, Singularity, and Synthesis papers; they are signposts outside the well-explored Unix/VMS territory.
