The only suggestion I would make is to make it possible to buy things through your site.  It seems like what you have is just a directory which we already have on the bitcoin wiki.  I would find it very useful if you had link throughs to some products on the sites in your directory.  Even better if I could purchase things directly through the site and then you could become the destination for all bitcoin spending (kinda like Amazon allowing people to sell through their site).


Other than that I like the idea.  I wish you much luck in your endeavor.
