1) I occasionally do things with other people, for example interviews. That's sometimes because I want to support them , because it's a favor, or what have you. Having them republished elsewhere without asking first is an anti-favor. I don't even republish my own stuff originally given to third parties without asking first.
2) I know there's a good deal of attempt here at curation to add value, and I appreciate the effort that went into that, but divorcing the answers from the questions in some cases does not capture what I think. I'd prefer to be primarily responsible for screwing up people's interpretations of my writing.
Now I know you Charlie and I know you're a good bloke, but in general, the outcomes are better for everyone when one asks for (and gets) an OK for this sort of thing.
