I'll make an answer with my own point of view, if only just for the record. The crucial question here is, which of the following options we want:
- any Christian is able to answer a question related to their own denomination off hand
- some questions can only be answered by experts, or require research
Now, I'm all for the second one. We should be a site where experts don't get bored. Maybe this is a question of opinion.
If we're to go for option 1, a lot of answers will be one-liners, and the worst ones will be along these lines:
- Yes, my church teaches so
- Just see John 1:1
- Me too
If we're to go for option 2, there will be questions that can't be answered by anyone straight off. A good answer for such a question might require referencing multiple sources and finding pros and cons of different arguments. Where I come from, Christians do this kind of thing; it's kind of the opposite of intellectual dishonesty. At skeptics.SE, some good answers follow these lines (not all).
What's the point, then? What does it matter?
- The internet is full of option 1 sites. Each denomination has a bunch of their own, and this goes on to almost all internet discussions where Christianity is even slightly mentioned.
- Option 2 is practically nonexistent. I don't know of a Christian community site where answers would often show expertise. (if you know of one, please tell me)
My guess is that with option 2, we are way more probable to survive beyond beta.
One good category of questions requiring expertise to answer would be questions of debate. I, for one, am very interested in hearing both sides in arguments like these. Answering will be difficult, I grant that, but that should be no reason. So what if we get the first answer only after a day or two? I'd be willing to go through the trouble of answering for some questions I find interesting. I'm sure there will be others.
I once heard a very good sermon-turn-lecture about the pedobaptism versus credobaptism debate that didn't take sides. This was in an interdenominational setting and left the Pentecostal and Lutheran believers present happy, so I think objective discussions are possible.
