If you use a Feedburner feed, you can combine your blog and feeds of popular web services like digg, del.icio.us etc. with a single click.
Feedburner Link Splicer lets you share your collected links in your feed. Splice your blog feed with your links feed from one of the popular link collection services like del.icio.us, Furl, Bloglines Clip Blog, My Web 2.0 or Digg. This service adds a new item to your FeedBurner feed that contains new links you have added to your link collection account. How often link items are added to your feed depends on a daily summary or whenever a link is added. Try it.
You can also try their photo splicer which merges photos in your Flickr, Buzznet, or Webshots account with your original source feed entries. Fid them both in your feedburner optimize options.
