As well as my "noderunner" mind-mapping protocol I've now ported the "statto" tracking and testing implementation to work with drupal. It doesn't need to track as much as with a metasite2 implementation because of how drupal's urls work, but the main components: ad-channel, page-variable and testo variable tracking and in-page testing are all fully functional within the drupal framework.

At the moment it's still in early testing but this is another significant step for me towards using drupal on a more serious level e.g. commercial sites.

I really hope I'm doing the right thing here but so far what I've seen of Drupal has been really impressive.

Currently my bottleneck is the actual building of sites - setting them up, making sure it all works as intended - the basic stuff which you need to be able to rely on in order to move forward. If I can remove that bottleneck that could revolutionise my work throughput. I'm hoping Drupal will allow me to do that.
