In the modern world of business, it is useless to be a creative original thinker unless you can also sell what you create. Management cannot be expected to recognize a good idea unless it is presented to them by a good salesman.
David M. Ogilvy

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
