I don't like reddit as a site, it's a for-profit social media thing with google and amazon trackers, it's buggy and unpredictable, and full of people spouting basically hate speech, calling it 'opinion'.
I like raddle.me, it's full of cool people, and the site just works.
The reason I still spend much more time on reddit is because I feel like I have an influence on what information people consume, influence on the culture reddit creates, and I can guide people to a better understanding of the few things that I understand.
Here on the other hand, I feel I'm not participating in the greater public discourse, I'm not guiding anyone to anything. If anything, I read and learn stuff from the links you post. It takes more effort, and it takes a while to digest new information.
Not sure where I'm going with this. Just some thoughts and a 'hi' from a lurker.
