Indeed, arranging a sort of blog meeting would be ideal for your purposes. People who read (and comment on) your blog are obviously interested communicating with you so you are halfway there for the friendship thing. You just gotta pick the ones you like :P Seeing as how most of us are Bulgarian, you'd also get to practice the language. I'm sure more than a couple of people here would like to meet you for beer/coffee and some stories - I for one would jump at the chance.
Also, I'd expect everyone would pay for their beer or whatever, andreytcho is joking :) And it's hardly desperate - forum meetings are common here, so why not blogs?
So go for it. You could ask here who would like to come, to get a general idea of the number of people, then pick out a place to go. Or set up a meeting at a park or something, then based on the turnout (and suggestions from "the locals" if needed), decide where to go.
