Thanks for the feedback. I'll go for a solid background. (ETA: Changed to timeless black to be a little easier on the eyes than some websites. Unfortunately I can't change the page's color to a light grey, will have to use some CSS. I'll consider further optimization later.)
You wording suggests you view these hypotheses as tools required to achieve some predetermined objective, rather than just as beliefs subject to observational revision.
Both and neither. I have many different epistemic practices, and I also try to switch up my epistemological approaches often. Coherentism, pragmatism, correspondence, whatever—ultimately I think the foundations of epistemology are to be found in decision theory, and any other epistemological approaches are just phenomenal shards of the fundamental nature of rationality. Hypotheses can be tools, hypotheses can be correspondences—whatever leads to intellectual fruit. "May we not forget interpretations consistent with the evidence, even at the cost of overweighting them." Similarly, may we not forget epistemologies consistent with potentially optimal decisions, even at the cost of overweighting them. We must be meta, we must be large.

Long story short, it's an attempt to justify the planetarium hypothesis as a solution to the Fermi paradox. The first half is a discussion of how it and things like it are relevant to the intended purview of the blog, and the second half is the meat of the post. You'll probably want to just eat the meat, which I think is relevant to the interests of many LessWrong folk.
The blog is Computational Theology. It's new. I'll be the primary poster, but others are sought. I'll likely introduce the blog and more completely describe it in its own discussion post when more posts are up, hopefully including a few from people besides me, and when the archive will give a more informative indication of what to expect from the blog. Despite theism's suspect reputation here at LessWrong I suspect many of the future posts will be of interest to this audience anyway, especially for those of you who take interest in discussion of the singularity. The blog will even occasionally touch on rationality proper. So you might want to store the fact of the blog's existence somewhere deep in the back of your head. A link to the blog's main page can be found on my LessWrong user page if you forget the url.
I'd appreciate it if comments about the substance of the post were made on the blog post itself, but if you want to discuss the content here on LessWrong then that's okay too. Any meta-level comments about presentation, typos, or the post's relevance to LessWrong, should probably be put as comments on this discussion post. Thanks all!
