Hello Andy. I'm a newbie here and I just wanted to post my vote! I'm by no means an expert, it's just that the topic really interests me as I'm trying to learn SEO myself.

I guess the reason why I chose Spanish is because of the different dialects that we have. In English, for example, there's American English, then there's London or UK english, and then there's Australian. In Spanish however, there are so many different dialects. I looked it up in Wikipedia and found about more than 70 dialects.

Colombian Spanish is different than spanish from Mexico or Spain. It's just that there's lots of different ways to spell a certain word, or put different accents on certain words.

So its difficult to optimize a site for the Spanish speaking crowd when someone from Peru might looks for a word that's spelled differently, or that might not even exists, in the Dominican Republic.
