We now have a nice Piwik open source web analytics 2min40 Promo Video
This way users could learn the feature of closing widgets, plus we get a chance for them to see it.
(In ) Fixes #3229, added widget that displays Piwik promo video. Added widget to default dashboard of non-superuser users.
awesome! This video in the default dashboard, will introduce hundreds of users to Piwik in a very nice and useful way.
I like the idea, however there are a number of countries where Youtube is completely blocked:
"As of September 2012, countries with standing national bans on YouTube include China, Iran, Pakistan, Syria, and Turkmenistan."
In these countries Piwik might not be very popular, but I still think it is worth mentioning that people will not be able to watch the video.
Ideally we would host the videos ourselves, I agree. WE also could have them for download as MP4... maybe later in the year we can host videos (and at same time, track Video metrics in the player using Piwik!) but not a priority now.
