Weblogs.com

Weblogs.com is a website created by UserLand Software and later maintained by Dave Winer. It launched in late 1999 as a free, registration-based web crawler monitoring weblogs, was converted into a ping-server in October 2001, and came to be used by most blog applications. Web-services like Feedster and Technorati monitor Weblogs.com for its list of the latest blog posts, generated in response to pings via XML-RPC. The site also provided free hosting to many early bloggers.
