A blog is an updated page, where information, such as articles or news, is published in chronological order by one or more than one author, generating debates through the sharing of opinions, comments or recommendations. Users have the freedom to create what they want to share, having the possibility of giving further information when it is necessary.
A blog is a very important tool for users, who are interested in related topics, because they can ask questions which will be rapidly answered. For companies, blogs are a source of information that can be used to keep in mind what the public perceives as important and what kind of innovation they are waiting for.
