What is New Weird Fantasy (aka Slipstream fantasy)?

What do you think? Are New Weird and Slipstream interchangeable in some ways? Do you consider them a kind of Fantasy? In any case, this article describes this style very well.

Quote: It’s a modern, non-linear, magical-realism type of almost experimental fiction, dancing between borders of science fiction, fantasy and mainstream literary fiction.
