By self hosted, I mean that you have to have access to your own server or webhost that is running PHP and MySQL. If you have ever installed WordPress, you can install Sweetcron. The only part that is a little more complicated was that the .htaccess file included with the installation needs to be edited if you aren’t installing Sweetcron at the root level of your server. In other words, if you install Sweetcron in a subdirectory called ‘lifestream’, you will need to edit this folder. On my first attempt, I did not edit the .htaccess file correctly and Sweetcron would not load. This problem, however, was quickly resolved.
What is nice about it being self hosted is that all of the feed data is stored in a database creating a lifestream archive for you. With some programming knowledge you can also be more creative and pull the data to your lifestream in unique ways.
The installation instructions are adequate and are available on the Sweetcron google code wiki so I’m not going to repeat them.
