Er - so there is a fair use defence for using short quotations from articles, but linking to the source so that the reader can see the whole context of the quote may be a copyright infringement? Sounds really sensible to me.
Annoying the US constitution is nicer about copyright, since it says that copyright is explicitly for limited time, and that it's to benefit the arts & sciences. Whereas the European Charter of Fundamental Freedoms (which was only enacted recently), just states that "Intellectual property shall be respected". No limits, no purposes. ☹
