Thanks Neo - they are a bit similar, but have more differences. SMT is
open source, Digg is not. You can't install Digg on your own site and
domain. You can install SMT on any PHP web server and resolve any
domain to it. You can add features to the SMT, you can't with Digg.
SMT lets you integrate stories, comments, votes and automated
materials into your site from the wider NewsCloud.com community and
other SMT sites for any topic. Digg is a standalone site.
SMT is more like Pligg than Digg - but still much more than Pligg.
