A blog is a
discussion or informational site published on the World Wide Web and consisting
of discrete entries ("posts") typically displayed in reverse
chronological order (the most recent post appears first). Until 2009 blogs were
usually the work of a single individual, occasionally of a small group, and
often covered a single subject. More recently "multi-author blogs"
(MABs) have developed, with posts written by large numbers of authors and professionally
edited. MABs from newspapers, other media outlets, universities, think tanks,
advocacy groups and similar institutions account for an increasing quantity of
blog traffic.
