I get the idea, but it was probably unrealistic to expect that Hoyerswerda would become a pilgrimage location for geeks. It is a real periphery from the point of view of DE, CZ and PL alike, and the museum didn't really do much to let itself known either. 30 thousand visitors yearly is 100 daily, that is quite a lot. You'd need to be known around the entire Central Europe to hope to reach such numbers.
I like exhibitions of this sort and I might have taken the 500 km long trip to see Zuse's museum, if I knew about it. I am only learning now.
