In life, the first thing you must do is decide what you really want. Weigh the costs and the results. Are the results worthy of the costs? Then make up your mind completely and go after your goal with all your might.
Alfred A. Montapert

A blog (or weblog) is traditionally an online diary, kept by an individual and recording their thoughts and experiences in a public arena. But the same application software is also highly suitable for more serious use by businesses for general information web-sites with news pages.

The main advantages for a business are:

  • a professional looking and fully-functional site can be achieved at relatively low-cost (compared to a custom web-site).
  • content can be easily updated by non-specialist staff – both the general information pages and news articles.
  • visitor feedback can be encouraged where appropriate through the comment mechanism, but comments can be fully moderated (ie. not shown publicly until approved by an administrator).

Preferred applications:

WordPress
