Syndicating someone’s feed ON your site is not an uncommon practice.
 
Notice at the top right-hand section of this page, we’ve pulled the RSS feeds of several different weblogs and podcasts. 

However, if there’s syndicated news on a blogsite, you can be assured it is there with permission of the owner of the site.

But, if you’ve blogged for very long, you know that many people will simply take your RSS feed and syndicate it on their site without your permission.

Knowing that, SEO-wise, some may not want their content duplicated, I’m sure you can understand why they might not be happy.

However, I complained about this to an RSS expert on Monday and he reminded me that by putting out full-text feeds I am inviting others to use my content as they see fit.  In fact, he chastised me for calling it feed hijacking, being that I have offered it up so freely and that the theives have given me a link back and not changed the original text. 

After talking I see his points.

He suggested going to partial feeds AND putting a fair use statement below each post.  I may just  do that.

He also said when I see my work on someone’s page without permission, I should send them an email and tell them I don’t want it used.  A follow-up form letter from my attorney might just remind them to take it down.
