Have been enjoying the demo for the new Twenty Twelve theme that we will all get our hands on soon. I really like that infinite scrolling on the blog page. I know infinite scrolling has been around for a while in various plugins, but I find it's inclusion into the new theme rather elegant (they did a really good job with that theme - so much more beautiful and useful than anything ever done before!)
Are Marketpress product listings pages (are these technically archive pages) compatible by default with that sort of feature? I see that it doesn't work on archive pages, so there are clearly limits to it, but I wonder if there is a way to connect this with MP? I could see some really elegant shops enjoying this function.
