Changing my posts to english

I'm considering change my posts (and my tweets too) to english. Some reasons to do this are:

• Open my scope (people from anywhere can read and understand my posts, not only lationamerica)
• The lack of comments to my posts (maybe the main reason is the previous one)
• Doing this, change the idiom for my posts, I can practice the writing for my article that I have to write to get my master

If anyone has any comment, please write it. Any doubts, or advices will be wellcome.
