I want to blog on my movable type blog from my iPad. The problem? If I take pictures on my iPad I cannot upload them to my blog because the blog doesn’t know where to find them on the iPad….

Is your web page managed by Going Type? If so, what are your thoughts regarding the update and why would you recommend it over competitive techniques.

I think the article may have confused people regarding extensions and plugins. You can extend MT without paying for stuff, though there will be paid extensions available as well - the same is true with a lot of OSS software.
