I think it’s easier to fling off some thoughtless remarks when you’re doing it on someone else’s site. I bet you that the discourse on Ev’s blog would be of a much higher quality if you could only respond from your own site. I find I’m more careful with my words when I publish here on adactio.com. I’m taking ownership of what I say.
Jeremy makes a great case. I syndicate my articles to Medium, but it made me think that I should probably be using Twitter as syndication as well.
