How about comparing the percentage of software developers in Spain to the US? Or discussing how the education for technology is different? Or what percentage of the unemployed are developers? Or software developer salaries compared to rest of EU. Or the number of Spanish developers working abroad or for companies abroad. Instead have a graph of Spain's GDP and a graph showing the size of their workforce.
This is why I rarely ever click on articles and only read the comments. Most of the time it's the only place with any substance.
