Blog is short for Web Log. It is type of website that is used as an online journal. Mostly updated daily, the blogs reflect the personality of the author. Most of the times the blog is personal in scope but there are some blogs which are related to just one specific subject like web design and web development blogs are very popular. Most of the blogs use blogging software like wordpress, movable type etc. Although blogs provide very good information on many topics but this information must be carefully evaluated because most of the times the content is personal views of the author.
