I know you want to check out some of those new themes on WordPress.com to see just how much they might make your blog shine, but you don’t want to activate any for fear your readers will get on your case about switching themes all the time.
… You have really obnoxious readers, don’t you?
Well no need to worry any longer. You can now preview any WordPress.com theme from your blog’s Presentation admin screen just by clicking on the theme’s thumbnail. Your blog will load on the fly using the new theme without actually activating that theme for realies. Even better, you can click around most anywhere in your blog to see how your posts, pages, categories and everything else look.
Kinda fun, huh? Go nuts.
