Many bloggers, particularly those engaged in participatory journalism, are amateur journalists, and thus they differentiate themselves from the professional reporters and editors who work in mainstream media organizations. Other bloggers are media professionals who are publishing online, rather than via a TV station or newspaper, either as an add-on to a traditional media presence (e.g., hosting a radio show or writing a column in a paper newspaper), or as their sole journalistic output. Some institutions and organizations see blogging as a means of "getting around the filter" of media "gatekeepers" and pushing their messages directly to the public. Many mainstream journalists, meanwhile, write their own blogs—well over 300, according to CyberJournalist.net's J-blog list. The first known use of a blog on a news site was in August 1998, when Jonathan Dube of "The Charlotte Observer" published one chronicling Hurricane Bonnie.
