Hi Wiktor,
I think the best thing you could possibly do right now is rephrasing this from the point of view of your target audience. Perhaps to repost and see if you get better response this time, but above all, this will be a useful exercise for you. It will be useful for two reasons; 1. it will force you to specify your target audience (ideally to a narrow niche of those you think will want to use this most actively) and 2. it will make you think about your service from their eyes - as a solution to a problem, not as a bunch of features. These two things should be part of the foundation of everything you do, particularly in such an early stage.
Reading about this service you want to provide, I see a few words about what it would be like, technically, but nothing about why I would want it. Try to make this your starting point instead. (I know you're targeting an audience of hackers with this post, but if you're asking if we want to pay for it, we'll want to know why we'd want to use it first.)
Does this help you?
