I find that there has been a decline in support via this forum lately. There’s a big difference between how it was, i.e., a year or two ago and today. I remember Matt who was replying to all of the queries, and I can only imagine what it takes to keep it going based on one person only.
No blame nor rant, but many questions sit with no credible answer which creates a lack of desire to use Piwik.
My guess is that it’s up to the community to get involved more in order to keep it going well. This is the only free well known competitor to Google Analytics.
