iBlogger seems to work reasonably well, though I don’t understand why links end up a couple of lines below where I try to add them. The link building form is a nice touch, but blogging from an iPhone really drives home the need for cut and paste.
The biggest drawback is that you cannot add photos if you use Blogger as your publishing platform, as I do. This feature is spposedly forthcoming, and it better get here soon. Photos are a must-have component in any iPhone app.
The jury and the camera are still out, but I think iBlogger has a lot of potential.
