There aren't that many people watching Universe live right now (around 2500), but they are very active in the live chat.
It's nice to read all those comments.

There's a girl who attended Universe back then when she was 6 - now she's 16 and (still) a fan.
People then also stated their age. 30,38, 40, 47, even a 13 year old, lots of different people watching.
Also some non-fans. One e.g. asked which DVD this is and another said he/she is not a fan, but Kuu's fans have the image of being cheerful/pleasent and he/she likes that.
