Unfortunately Sweetcron has been officially abandoned by its author. Hence documentation is poor and scattered. I will list the main resources I found: tutorials, screencasts, tips and whatever was helpful in developing my own Sweetcron lifestream. I hope this will help you as well, helping beginners to start and hopefully interesting "power users" as well. Feedback is welcome, please use comments below.

Quick start

“ Sweetcron is an open source lifestreaming blog software created by Jon "Yongfook" Cockle based on the CodeIgniter framework. It was originally released on 3 September 2008 and the latest version following on 22 September. Sweetcron is similar to other web applications such as Tumblr and Friendfeed, but users are able to host their own lifestream on their own server and customize it in any way they want with the Sweetcron API...”
