Here's a 100% free way to improve your Spanish, boost your "slang" quotient, build vocabulary and learn to use expressions as natives do - read Spanish language blogs. (And leave comments in Spanish!) If you're truly committed, you might want to try your hand at writing one...or perhaps a bilingual blog, for other students of Spanish in your country?

You can set up your own Spanish language blog at Bitácoras.com . Blogger offers a full (free) Spanish language blogging interface, as well.

Here are a few resources bound to help you identify Spanish blogs you'd like to read regularly:

Bitácoras offers a list of the 500 Best Blogs in Spanish.

The same site also keeps a great archive of interviews with Spanish language bloggers.

Here you'll find one blogger's ranking of the 100 best blogs in Spanish.

And on the offical page of the Bobs (best of the blogs) you'll find a nifty tool you can use to search for blogs by language and topic.

¡A la blogósfera!
