Third party blog post content for affiliates?
 

I find blogging effective in promoting sponsors, but I'm not sure sponsor RSS feeds are (currently) really as effective as individual blog posts by affiliates.

The affiliate blogs have greater opportunities visa vis search engine traffic (blog and traditional) and surfer stickiness.

With that in mind:

1) Is there any interest in blog posts written to promote specific sponsors (including affiliate ids) which affiliates can acquire (just like any other authored content) and paste or import into their bogs as they choose?

2) If so, in which format would pre-authored blog posts be of greatest value:

2a) Simple text file with title and body of each post for easy cut/paste?

2b) XML file which can be imported into WordPress?

Thanks :)
