Principle of blogs
A blog can be defined as a virtual diary that blends the functions of a forum and a personal page. This personal page consists of a series of remarks or periodic information published by its author that readers may respond. The blog can also contain pictures or attachments.
Very few blogs can be very popular as the editorial of a press while others, which constitute the vast majority, have a hearing as confidential. The update frequency is variable and depends on their authors, many blogs are however updated daily.
The blog itself is not new because personal pages updated every day played the same role. The term blog and its use has actually been popularized from the end of 2000, when free online services appeared to help users manage without any technical skills and intuitively these new virtual diaries.
A blog is hosted by personal means or is hosted on a specialized site that offers free accommodation. These niche sites are sites born with fashion blogs or sites specializing in hosting forums or personal pages for which the creation of a blog is a natural activity.
