I haven’t been publishing about many changes in Feed Friends and I can’t really remember everything I did but today I finally got tired of link toolbar to only have Feed Friends share button and not to have Digg, del.icio.us and the rest so I changed this processor to include all In-Feed Controls I configured in processing customization page.
So, even if you don’t use Feed Friends sharing functionality, you can still enjoy Feed Preprocessor part of the system and use it to get If-Feed controls to work for you.
P.S. Actually Feed Preprocessor configurator allows you to pick more controls then listed on infeedcontrols.com and they include: del.icio.us, Technorati search, Digg, Feed Friends, Newsvine, Fark, Reddit, Yahoo! My Web and Netscape.
