A friend just said on Twitter (and another cross-posted his agreement from there to Facebook), that magazines/newspapers/radio stations should ask permission before quoting from Twitter and Facebook.

I go back and forth on that. Both as a twitter contributor and a blogger who needs to quote Facebook and Twitter. Quoting from email or conversation, I am bringing something from a private domain into the public one; but when I quote Twitter or Facebook, I am quoting something that anyone can see anyway, no?

Unless it's a protected tweet. Then maybe it makes sense to ask. Also, some times I think one should ask permission if one wants to link to a status, particularly on Facebook.

And I didn't ask either friend for permission before writing this comment. Was I wrong?
