Yes, we consider serving questions to be on topic, as long as they're the kinds of questions that would require at least some level of experience in the culinary arts to answer (which is why questions about topics like dinnerware and etiquette are not in the scope).
As far as I'm concerned, the fried egg question:
Was not reasonably about cooking or serving (it was simply about eating);
Did not inspire any edits that would have made it about serving (otherwise someone would have done it);
Had already amassed far too much attention and voting activity to salvage with such editing, even if it were possible; and
Was liable to generate a slew of copycat questions about eating any other food ("How can I eat a burrito without leaking filling?" "How can I eat a hamburger without squirting ketchup?" Think about where this ultimately leads.)
We had a series of long, frustrating arguments about these kinds of generic food questions early on and eventually came to the general agreement that we had to set the bar somewhere if we wanted to be taken halfway seriously as an expert Q&A site. The topic being discussed just doesn't meet that bar.
Questions here are supposed to be about cooking or food preparation. Yes, we'll accept some serving questions, but they have to be good questions - questions of interest to professional or enthusiast cooks. That's why the FAQ doesn't explicitly include this category; we don't want to encourage it across the board. Food presentation is about making meals look attractive for guests, not about how to eat runny eggs without getting it on your hands. Sorry.
In closing, if your question refers to eating food that's already been cooked (or prepared for eating) then please think long and hard before posting it here, because it's likely to get closed. That's not legitimately in the "serving" category; it's Yahoo Answers fodder.
