I think one tool that is WAY under utilized is the HiveRSS feed that is maintained by @hivetrending from the Hive Pizza crew.

It's an AWESOME resource for people to be able to easily tap into the database without having to really know any code. I have used it on my Wordpress installs and actually redesigning the @hivelist classifieds home page on the Wordpress side of things that will pull Hivelist on-chain posts and when clicked on, it goes to the on-chain side of things, which isn't nearly as customizable than what I can do with WP.
