i are bored always visiting the same sites I recommend this tool. StumbleUpon called and it is a bar that is installed in your Firefox or Explorer browser by adding a series of buttons.
The first button is Stumble! and every time you to do click it will go to a random website. If you like the site you click on I like it! and if not in the hand with the thumb down. Depending on your votes (and that you will make the log-in before on his website) the system will learn what you like and what does not. What it does internally is to compare that information with from other users and will refine the recommendations and sites that send you. You can also choose the categories that you like from dozens there to filter the results somewhat. The bar has a few more options: puodeis see other users who like the same page that you are watching, reading mini-reviews I write about themselves and others.
By the way, you can also choose the language in which you want to look for the websites by clicking it in and All Languages \u200b\u200b.
Personally I love this tool because it leads to very interesting sites that otherwise would not find and it is really addictive!
