commenting

Commenting an article - below article or below article+other comments ?

Hi,

I'd like to hear your opinion on where to place a form to comment an article:

1. Directly under the corresponding article (and above existing comments)

2. All the way down under both the article and the existing comments

I have a feeling it depends...

If you happen to have any examples, supporting research for either option please share :)

Thanks,

/Jakub:)
