I'm using SN as my bitcoin news source more and more. I don't use Twitter as much as I used to. If article links decrease on SN I'll be forced to go elsewhere. IMO that would be terrible, since I think SN is the future on so many levels.
I try to focus on posts with original thoughts/content. Especially artwork. Those posts deserve tips. IMO posting a link to another site/article is kinda lame.
