Google's +1 button has seemingly had the result desired for the search engine, as today sees its proportion from the US to the UK, France, Germany and Japan, with the rest of the world following shortly.
The +1 button is a fairly new addition to Google's arsenal of weapons in its never-ending fight against content farms and other low-quality websites. With its launch internationally, the same results tuning that +1 has been affording to the US search results pages can now work its magic on all of Google's localised, international results pages as well.
Of course its not just Google that benefits from the better search results provided by the use of the +1 button. Sites producing quality content, and with a loyal reader base could well see their rankings improved. And as +1 users' recommendations are flagged to friends on results pages, it's possible that sites may see increased traffic, too.
Once again, a large number of publishers are on board, including the Telegraph, the Independent and Last.fm in the UK. Of course Google is keen to point out that those not among the sites involved in the debut of the +1 button internationally are encouraged to add it to their own sites.
Semi-related, but more light hearted, is a new Google site called "What Do You Love?" and asking that same question. The results page pulls from a wide range of various Google properties, giving a broad overview of a topic, and with the right query can produce some amusing results - you may as well check it out.
