My absence says it all. Coding/blogging isn't really practical when there's a newborn cradled in one arm. ;)
Still, I've been a busy bee on Piwik, especially now that I have commit privileges. ;) We pushed 0.4.1 out the door primarily to address issues raised by PHP 5.2.10, but there are a lot of other fixes as well, in addition to now being able to manually (programmatically) trigger a goal from the browser.
You can't believe everything you read on Twitter. There were tweets purporting that the Ontario Ombudsman's office had adopted Piwik for its web site, but I just checked and they're currently using GA. =P
