Hi Hansi, I'm really thankful for the feedback. We'll work on creating a page with additional information (FAQs).
You're right about one thing -- the service is very much incomplete. Our philosophy is to continue to talk to customers (hackers and companies) and minimize the amount of building we do without their blessing.
In terms of the limiting the network size, we know we're going to encounter problems (we're counting on it!). As a result, we want to make sure we'll have the resources to spend time with each of our customers during early alpha stages.
I'd love to hear your feedback on how we can improve the site. Do you hire contractors or are you looking for opportunities? Let me know how I can help.
