I believe that most people really want to be able to help others if they have the means to do so. When reading the "about section" of Aidpage; I certainly would be one of those people stopping to help someone asking for something as simple as directions. But in the "face to face" world, you're provide an opportunity to assess the situation yourself, by observing. And then make a judgement call, and respond accordingly.
This reminds me of the story of the Good Samaritan. Many passed by the injured individual - even those individuals that you typically think would automatically helped. But it was a Samaritan that helped this person in need (even though the person in need was from a race that typically treated the Samaritans poorly).
So in the world of the internet, I find being a good Samaritan a little more difficult. How do you know which request are sincer? This site, Aidpage, I find interesting because its primarly providing "moral support" or pointing someone in the right direction. I don't know if I know the "right direction" but I'm willing to try this webstie as a good place to explore this approach via the internet.
