Tips From my WordPress Book
A good post title clearly announces what you are going to discuss (p. 95)
Make sure your content is worth reading (p. 105) e.g. interesting or useful
Add new content regularly –“avoid stale content.” But an observation, what’s wrong with that? — posts are dated. Maybe it depends on the topic.
Keep your content organized. “A good blog is ruthlessly arranged using categories and tags,” since browsing through monthly archives or searching for keywords in a post are not that convenient.
