Thanks for the reply!
The original plan was to reveal more about our site on that additional link, where we will try to answer those questions that you mentioned and some others. For that matter, your reply is very valuable to me as it comfirmed that we would have to focus on that.
We'll work on improving the explaination, but the problem is that we don't want to reveal too much.
Obviously, we will have to explain it better, so we will look for just the right amount of info, that will feel comfortable for us at this stage and at the same time enough to intreague people.
