I hate to say it but the GUI looks terrible.

In other words, on the iPhone you have to go to lengths to polish the visual look and layout of your UI to be on par with the successful apps. If you can't see what's "better" in these apps then it might be time to get yourself a GUI designer.

There needs to be some bolded text in there somewhere. First choice would be the question title. The extraneous information such as username etc should be a grayish color. If you're going to have the votes box in there, the question title needs to at least be in line with the top. There's many things that make your mock up flat and unpolished. The votes box for example could be more than just a flat rounded rectangle. Or it could take up the whole height to make a pseudo two-column table.

Consume you, the brackets will.
