Question: where can I get free headlines for my site?

There are many freeservices offering free news tickers and headlines for the public-- so many, in fact, that a directory named Freesticky.com (see below)  has an entire category dedicated to them. Besides checking it out, you can also do a search at Google to choose from a large selection of free newsfeeds and headlines, which are often offered by many content and news sites hoping to promote their web sites.
