As for the ones that have completely waken up, yes, language barrier is the problem. Older people speak only russian as a foreign language and the younger ones with poor English skills are even more isolated. That's the sole reason why I brought http://www.tunnistaja.ee into existance - it adds nothing new to jwfacts.com, jwsurvey.org and such, but it's a little place to start from for those who only read and Google in Estonian.
I'm also probably attending the meeting in Suomenlinna on June 7th, so we can have a longer chat about all that there
