I do not know English and I use the translator, that limits me a lot, I only post in Castilian, but there is a big disadvantage because the Spanish language in that sense is a minority here.
And if you are right besides that, what would be of this site if there are only blogers and more bloggers with text and more text? That would be something completely boring, diversity is good because we are all different and unique.
You'll be good with Spanish. A lot of people in world speak Spanish. Just wait for a while, they will come.
