You know what I do?
When I see things that I'd like to add to my post that are of that nature - I simply put a link to THEIR site. That helps everyone
No one should be coming to my post to give me the activity for THEIR content. They can read my take on it - my views that I've added - but for the actual content itself - I don't just drop it into my post. I drop the link that drive traffic back to THEM and say - here you go if you want to see more.
I think that can be a valid compromise
Yeah that is what I try to do as well! Reblogging etc is one way we can help propagate valuable content as well. There are ways we can make it work for sure.
