A blog can be installed within minutes with the right host and the right type of application. However, there are choices to think about before choosing the right content management system for the blog itself.
First off, think of the things that need to be available on the blogs. Will there be any videos that need to be uploaded? Or will there only be text and pictures. Do you also need a plugin to put the advertisement in place and is it achievable with the content management system?
If the answer to all of those questions is yes, then you will be better off with WordPress. WordPress has a lot of features that would suit any blog owners. Users can embed videos and even play with some of the plugins that are available on its site. Most of these plugins are free so there would be no harm in trying them.
Try getting hosts that have an all-in-one installer in the control panel. Most of the hosts today are equipped with these programs and a good example of it is Fantastico. Installing WordPress in Fantastico would be a fast and painless experience. Another good example would be Scriptaculous. These two applications would handle all of the installing themselves and all there is to be done is a few clicks on the mouse.
