Ask HN: Today, Croatia is voting on joining the EU. What are your thoughts?

Today in Croatia, we're having a referendum on joining the European Union. Both the proponents and opponents are loud, although the polls seem to be in favor of the pro-EU side.

What are your thoughts about entering, considering the problems the EU currently faces? I've seen plenty of HN-ers from Slovenia, Bulgaria, Romania, and other countries which recently went through the process. I'd very much like to hear about their experiences, especially about the way it affected startups and small companies.

Thanks!
