I think that this program can be potentially dangerous- it has an explicit Facebook link in the tool-bar, which, if hit by mistake, will open Facebook and thus infect the system- unfortunately not many users know what is "datr" and what it is doing.
I have no respect for developers who have Facebook pages and promote them. Twitter is fine but Facebook was never, is not and will never be fine.
