If it wasn't displaying news on my own network, and was DHTML based (thus not introducing much content of value for SEO), I don't see any reason to intentionally lead users away from my site with a potentially uncool news thingie.
I definitely pull news from my own sites though and display the latest headlines on my network.
It depends. I wouldn't want to detract visitors from a sales type website but I do use a RSS feed on my investing membership site to use the credability of big names from other fortune 500 companies.
