I gave a link to someone at some point.
I was criticized for not explaining what the link was about.
About this question: Should Artists Have to Talk About Their Work? – I think the answer is „No, you don’t need to explain your work”.
If I give a link to you, you should try and wonder why did I gave the link to you.
If you don’t find an answer, ask me.
But I don’t start with the assumption that each time I give a link I have to comment on it, just to make sure the person gets the message.
Sometimes, a bit of obscurity is fine.
