Yeh. You can now read this blog on your Wii in Opera. Check it out and lemme know how it goes.
There's a Wordpress plugin that will reformat the theme of your blog when viewed on a Wii.
The Wordpress Wii Edition Plugin Site says:
Why is this plugin useful?
Webpages on the Wii are hard to view on default zoom and on many pages (designed wider then 800 pixels) you will have to scroll from side to side. In addition, font sizes that work on a computer screen don’t render well on a TV screen. As such we put together this plugin to make our favorite blogs a bit easier to read.
Other Wordpressers should get on this. AND Wordpress.com should do this automagically for the folks.
