'Publish first' is common everywhere, it's just... it seems to make people go a bit weirder in the SCA. I can't put my finger on what the difference is, but it seems to be a lot less self-confident for SCA folks who feel that without being given credit for finding a pretty picture, they're not as valuable.

I believe I know the re-posting incident you're referring to. And I have to admit, that I wanted to shrug and say 'you put this information in a publicly accessible place, what did you think would happen?' When I was running a website about Baltic stuff (which I need to put back up online really...) I honestly didn't expect because I made the website that I would get some sort of magical credit for what I did. Certainly, I put my name on it to say 'I put all of this together', but that's it.
Obviously people feel differently about this, I wonder if it has much to do with the differences between, say, Arts and Science (undergraduate) training.

In Arts, you put in your bibliography _everything_, including that blog that had lots of cool links to resources that you also whacked into the list.
In Science, you will get marks deducted if you include sources in your bibliography that you didn't directly reference in the text.

It's a complex issue, and probably somewhat off topic. :)
