It's only been ten days here but I gotta say the proof is in the pudding: I log off from here feeling good and more motivated than before. I log off from the other ones feeling foggy headed and brain assaulted. 

Also when you go to the other apps after spending time here it feels like you stepped back in time 15 years from a UX perspective. Like you walked into a gaudy casino that wants you to gamble away all your IQ points.

The north star for any social project should be how it makes people feel. I can't say exactly why yet, but this place seems to be succeeding on that front so far.
