We have even fought hard to defend your privacy in legal cases; however, we've done it with almost no financial support -- paying out of pocket to continue providing the service. Due to the issues imposed on us by advertisers, we also stopped hosting most ads on the forums many years ago. We hope you appreciate our efforts.

Laskinpa tuon virhemarginaalin 8 ov tilastotieteen taidoillani. Luvun oikeellisuudesta en mene mitään vannomaan...

Virhemarginaali on 4,7 %

Kun joka viidennes tarkoittaa 20%, niin 95%:n todennäköisyydellä suomalaisten luomun käyttäjien osuus on välillä (15,3 ... 24,7%)
