@Inge and @Uli, thank you for really nice advices.
I definitely agree that we haven't kept the campaign updated and I will hopefully update it today.
As to the crowd: I would say we are not working that bad on the promotion. So far, we got á 1500 fans on Facebook (we tried to use paid promotion also, but dind't work for us that well and organic reach was much better) and I see Twitter as a complementary platform, which aims to slightly different target group.
Thank you for the Facebook groups – since it is quite difficult to cover all of them and I didn't see these.
To our crowd and the communication then: we are mainly targeting to young travellers 20-30 yrs old, who might also be interested in Georgia or have been here before. I have been choosing the groups to post according to this and I definitely use lot of them. Then, we are getting lot of help from travel bloggers and related organisations, who are promoting us through their pages. Also, I launched a direct emailing campaign, since I have emails of around 250 young travelers, mainly Slovakia and Czech Republic, who I have cooperated with.
We are also asking for contributions personally – aiming this approach mainly to owners/managers of the places which will be included.
I definitely vote for a meetup, would love to get to know you guys :)
