Words without context get boring quickly; words with context and purpose and emotion are interesting. Narration is hard to keep interesting for a long time, imo, because it's detached.
On your page, you ask:
i want to know what you guys think, would you rather learn a bit more about the main character now, or learn those things about him later on? no real editing would have to be done to just omit the page, it is really dependent on whether you want the real story to start this upcoming page or the one after?
But this is a question only you can answer. It's a storytelling question. When do we need that information?
You have to look at your story and ask yourself -- will learning this info affect our view of the character, right now? Will it affect how we see him, and how we understand his actions? And will that effect be good or bad?
Here's a good example: In Finding Nemo, because we start with the dad fish losing his wife and all their babies, his ridiculous overprotection of Nemo when "the real story starts" instantly makes sense to us -- he's scared to lose the only family he has left. Without that scene, the dad fish would seem obnoxious, and we'd identify more with Nemo's frustration, and it would be harder to get into the story.
The information (Nemo's mom & siblings are dead) isn't as important -- we could follow the story without it -- but the implications (Marlin has lost everything he loves) affect how we understand the story, and that's VERY important.
For the opposite example, I like this one I heard about a movie I haven't seen (Trains, Planes, and Automobiles) where Neal is stuck travelling with Del. We're supposed to find Del annoying, so it's played for laughs that he keeps stressing out Neal. Later in the movie, we learn that Del has lost his wife and is lonely, and the two reconcile. If we had started out the movie with that information, like in Finding Nemo, and understood where Del was coming from, it wouldn't be funny when Neal was annoyed -- Neal would just seem like a jerk. It would mess up the flow of the story.
So, TL;DR -- you gotta figure out how this information affects the way we understand your story and your character, and THAT determines whether you should reveal it now or wait until later. Will this exposition show us something about your character, and is that going to help us identify with him? Or would this info be wasted because right now we're not invested in your character yet and won't care?
