I Have 5 blogs. One is all Press releases and Promotional Material that is sent in. Easy to update. One is static, just using the blog template as a landing page. I only need to update newsletters, and new products. One requires a lot of work because it has many front page categories that need constant updating. One is severely neglected. The last one will also be static. Working on it today
