Previously, a knowledge of such technologies as HTML and File Transfer Protocol had been required to publish content on the Web, and as such, early Web users tended to be hackers and computer enthusiasts.
In the 2010s, majority are interactive Web 2.0 websites, allowing visitors to leave online comments and even message each other via GUI widgets on the blogs, and it is this interactivity that distinguishes them from other static websites.
Others function as more personal online diaries, and others function more as online brand advertising of a particular individual or company.
is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries ("posts").
Posts are typically displayed in reverse chronological order, so that the most recent post appears first, at the top of the web page.
In that sense, blogging can be seen as a form of social networking service.
MABs from newspapers, other media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog traffic.
The rise of Twitter and other "microblogging" systems helps integrate MABs and single-author blogs into the news media.
However, there are high-readership blogs which do not allow comments.
Many blogs provide commentary on a particular subject or topic, ranging from politics to sports.
Blog can also be used as a verb, meaning to maintain or add content to a blog.
The emergence and growth of blogs in the late 1990s coincided with the advent of web publishing tools that facilitated the posting of content by non-technical users who did not have much experience with HTML or computer programming.
