1. Submitters. I've submitted many questions, when I do that, the only thing I care is to get answers, probably from as many people as possible. I really don't care whether it's front paged. What keeps me coming back is that all my questions so far have gotten satisfactory anwsers, in contrast to some other sites. So I think the most important thing PM needs to provide is to make sure most questions are answered. Sumitters are PM's customers, keep them happy, everything else doesn't matter. If frontpage is the way to do it, so be it.

2. New comers. This is PM's growth strategy, how to attract new users. I came to PM before, looked at it, and went away. I only came back because I had some questions that I couldn't get answers, and thought I'll give it a try here. Now I come back every day because my questions are answered, plus now I can sometimes even help someone else. I'd say PM should strive to have the reputation as a place where questions are answered, not necessarily as the place interesting questions are asked. In other words, a frontpage with interesting questions is fine, most important is whether my questions are answered regularly.

3. Regular users. I'd suspect most of the regular users use Newst Nodes, so front page doesn't really matter.

4. XP whores. Grow up, and find a life:-)

So, I'd say, keep it as is, I'm a happy customer so far.
