by one of the biggest issues with having a forum is its so hard to find time to keep up with it if you got what to say then a blog is great if just make it and forget about it it doesn't add to much to your site. its just a great way for you to tell the story of you site.

i know at our school we find it realy hard to find the time to say anything that means anything as i don't want to spend to much time on things that aren't actually the work of the site itself! ha its a catch 99 sometimes.

Through blogs, you can simply drive traffic to your site by creating good content.
