In one of my recent endeavors while understanding and addressing the Web2.0 fundamentals I came across something which was more fundamental than I thought, a simple question “What is the difference between syndicators and aggregators”. Here is what I found
News Aggregator: A news aggregator is a software application or remotely hosted service that collects syndicated content from disparate sources and provides a single consolidated view. These applications can also be commonly referred to as a feed reader, feed aggregator or simply just an aggregator.

News Syndicator: In general, syndication means the distribution a news article through a syndicate - in this case an RSS feed - for publication in a number of newspapers or periodicals simultaneously. Used in the context of RSS because RSS syndication is all about distributing content for reuse or redistribution on other websites.

Some other definitions from Google -
News Aggregator: Aggregators, such as NewsGator and AmphetaDesk , allow users to subscribe to feeds from sources as diverse as the BBC, Sci-Fi Today, Slashdot and thousands of bloggers across the world. The services work by checking an Internet address at a regular interval, usually once an hour, to see if new content has been added. …
News Syndicator: The process by which a web site is able to share information, such as articles, with other web sites. It is an alternative means of accessing the vast amount of information that now exists on the world wide web. Instead of the user browsing websites for information of interest, the information is sent directly to the user.
