Why some blog features may benefit CDEA.
Blogs tend to be
transactional - ie. you create, publish and have to let it be. Much like accounting transactions. Which you have to void by creating a identical transaction with opposite sign.
Chart of accounts tends to be
hierarchical. Many weblogs are using OPML to organize xml-feeds.
Weblogs have
flags for unread posts. It could be convenient for manager to mark read transactions.
