But since I've started blogging, my English has improved a lot, naturally. If you read my poems written before I've started blogging, you'll realize a lot of grammar mistakes.
Blogging improved my English because
I read other blogs - Usually, when you blog, you'll read other blogs too because you want to know more about a certain topic of your interest.
(Further more, if you use twitter, you'll discover many links to interesting articles, which means more reading!)
I write - Writing is simply a must to become a better writer. You know I don't need to explain this :P .
In conclusion, read and write and your English will improve naturally.
