Ask anyone who's achieved proficiency in a second language and they'll tell you submersion is key. While most of us can't pick up and move to another country just for our language-learning benefit, you can submerse yourself on the web easily enough.
Weblog MakeUseOf suggests changing your browsing habits with popular web sites like Amazon, using foreign-language version of these sites to keep your mind on your education during normal browsing.
You see, these large websites generally use simple sentences and popular words. Take eBay; it doesn't have many long rambling paragraphs, rather just plain words and phrases. All of the different categories will undoubtedly be useful words and what's more they're often associated with pictures. You can also get a bargain on expensive products on native language sites where demand is lower.
The idea behind the suggestion is sound even if you don't actually place an order.
The MakeUseOf post also highlights a couple of other suggestions to motivate you in learning a second language that may be worth a try, like previously mentioned BBC Languages. If you've tried something similar to their web site submersion tip—or you've got your own tips for what worked for you—let's hear about it in the comments.
