Thank you for the answers, I really appreciate it!
Before writing that post, I wasn't aware that there are so many posts with the #spanish tag. I thought the leader was #kr and #cn. Now I found out that most users are from Venezuela, and I still thought that it is more or less equally distributed across all Spanish-speaking countries. I am aware of the economic situation in Venezuela, but I did not expect it to have an effect on Steem!
And thank you for explaining the issue of #spanish, #cervantes and #castellano tags, because I couldn't figure it out myself :)
Saludos desde Polonia!
