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.

This program I wrote in 2008 and I am developing it until today. It cost me a LOT of work and time. And you write that you do not respect me and my work, only because I've added the "Facebook button" to the toolbar. Thank you very much!
