The problem is that when you want to share an article you found on a website to interested people on bitcointalk, there doesn't exist a way to do it. The alternatives don't accomplish what you want.

1. If someone wants to share an article and posts this:

Most of the people who you want to read it won't, because they are apprehensive of clicking unknown links.

2. There is no "Share" button on bitcointalk where you can send an article you read to a new thread for others to read (such a feature would be heavily abused too).

So I think the best solution is, to include the sentence "I am not the source, this information came from the following articles:" at the end, before the list of links. Even though it is generally accepted that including links to articles you derived information from is a form of attribution (and attribution absolves you from claims of plagiarism), it looks like some people overlook this, and want to see a more prominent form of attribution.
