CAT Did you imagine it?
When thinking about software, people often believe good apps and platforms come only from the other side of the ocean.
They simply don't know there is plenty of very good ones from Europe, especially open source ones.
Of course this is not to be taken strictly, as open source projects are among the most charmingly cosmopolitan stuff with people collaborating often from all over the world.
Yet many of them have been started in Europe.
And here are some.
