After getting this new blog up and running, I noticed one of the features that was added in version 2.5 of WordPress: revisions. It got me to thinking about how the database was impacted after moving all of those entries over. After running a query in the DB, the result came back with 1723 rows, yet I only have 684 entries. The rest (minus pages and attachments) were all revisions of blog posts and pages. Each revision is a full blog entry. Over time, that could add up to a lot of data, depending on how often you post entries and how many revisions you create in the process of each post.
