(Image Caption: HuffPo-To-Go: The mobile app for HuffingtonPost.com looks a lot like the Web site. But on an iPhone-sized screen, that's not necessarily a good thing.)

The app for the iPhone and iPod touch looks and feels a lot like the Web site, with its bold heads and lengthy sub-headlines. But the app suffers from a number of technical glitches that make it an unreliable mobile news companion, falling somewhere between the generally slick (if slow) news delivery of the ( Macworld rated 3 out of 5 mice ) and the slapdash and clumsy effort of the ( Macworld rated 2 out of 5 mice ).

The delivers the same content for your handheld as you would find on the Web site, including videos and audio clips. Nothing is held back. Some of the graphics appear badly rendered, and the colorful headline type looks simply ridiculous on the smaller screen. In the app's blog section, one or two-word headlines appear next to mugshots without bylines or any other contextual information, which makes for a bizarre browsing experience.

Using the app for even a short while, it's hard not to get the impression that the Web site's content hasn't been optimized for a handheld device. I also noticed that the navigation buttons at the bottom of the screen seem to be invisible. A system 3.0 update programming glitch or nefarious Republican plot? Hard to say, though I'd lean toward the former. Also: You need a Wi-Fi, 3G, or EDGE connection to use the app, which doesn't support offline reading.

HuffPo is not as hip to the social networking scene as I would have expected. You can e-mail stories, and the app syncs with Facebook Connect, which is nice. But you cannot post to Twitter, which is not so nice.
