There's a sporadic influx of questions that aren't travel related appearing on the site.
Example: Are there any standard clothing restrictions when visiting mosques?
There's another about safe ways to eat fugu. Another about a particular bungee jump.
The problem is that there's a genre of questions that one would argue are "on-topic" if you start them with "I'm traveling to xxx and would like to know...".
These are really bad questions to allow for a beta site because they don't attract expert travelers. Who are expert travelers? People that know about flying, miles, award points, hotels, etc. This is a community that has people that belong and people that don't belong.
This site could become a place to ask about any destination a la trip advisor but it would need HUGE critical mass before that happens. And the only way we're going to get critical mass is by starting to attract the smaller group of hard core travelers.
To get the hardcores, we need to start with questions that appeal to them and not the random vacationer.
