Typing on the Wii is probably not the most fun thing you could do but it does work. I’m impressed with the web browser, Opera, which works very well even without using all of the available input methods.
WordPress works pretty well but don’t expect to write a quick post–typing by aiming a remote at an on-screen keyboard is not even in the ballpark of quick–and forget about formatting.
Better yet, don’t blog from your Wii. It’s just not worth it. This took forever.
Another plus: AJAX works. So does dbx.
