i like it. like i mentioned to you before, one of the previous site updates had introduced some processes or functions that were slowing the browsing on my iphone to a crawl. that's all been alleviated with the stripped down mobile version.
the only thing i can think of off the top of my head to improve it is to include the "recent topics" box on the mobile homepage. i'm not sure how much control you have over the layout, but this is probably the first thing that regular users look for upon visiting the site.
