Should blogs and RSS be a part of your lead generation strategy?

Scoble's Link Blog pointed me to this interesting article by Pheedo's Bill Flitter, "A Sound Case to Include Blogs and RSS in Your Marketing Mix."

Flitter writes, "I've listed below the more popular on-line lead generation techniques employed by marketers today. We'll examine each and provide tips on how a Blog or RSS strategy can compliment what you are doing today." 

Bill addresses the following lead generation modalities; white papers, search (SEO), display ads, email newsletters and public relations.

I agree that Blogs and RSS will continue grow in importance (as lead generation tools) but, I'm not sure that they will replace any of these modalities - at least not yet.
