Is there a simple way to notify users about new posts on the site? I want my users to be able to "subscribe" to new content that is posted on my site.

I've looked at the Notifications and Subscriptions modules and they are just massive! I've also looked at Simplenews (which which has a very attractive name), but it seems targeted towards distribution of a custom newsletter and not sending out general notifications about new content posted on the site.

Is there simple a way to set up a rule (by means of the Rules module) to accomplish this?
You may consider the Notify module, which is a lightweight framework for sending out periodic notifications about new site content to users and admins.

From the project page:


  The notify module allows users to subscribe to periodic emails which include all new or revised content and/or comments of specific content types, much like the daily newsletters sent by some websites.
