Time will tell, but blogs are ideal for snippets of news, ideas and other bits and pieces. As a visitor you can add comments to the posts in the Blog by clicking on the comment link which follows each of them. You'll need to register in order to post comments - the first time you click a comment link a page will appear which enables you to do this.
