Writing Posts on an iPod Touch 

I read blog posts on my iPod Touch using the Netnewswire application. But how easy is it to write a blog post on the device? I’m typing this using my thumb – it’s not as quick as using a keyboard but isn’t too difficult.

I normally restrict typing to Twittering, but can I use my iPod Touch when I wish to write longer articles? Or should I buy a keyboard?
