This kind of service is actually great.
But what I observed was, the continuity of this type of project.
What I meant by this - if the developers will still continue to develop even if they will not raise their targets?
Do they really have the capability/expertise to advance the project?
Do they really have intentions to create and make a difference?
This is not the first time to introduce such kind of platform.
But very few attain their success because of lack of funds, lost interest, etc..
