Believe it or not, Picasa Web Albums is a big success outside US and, since the interface is available in 38 languages, many people post comments in their native languages. Click on a featured photo and you'll certainly see at least a comment written in Spanish, Italian, Chinese, French or other language.
Google's photo-sharing service started to use Google Translate API to automatically translate comments in your interface's language. The translation is displayed below the original comment.
Of course, the translation is not perfect and Google didn't do a good job at properly disclosing that it's an automatic translation (there's a "Powered by Google Translate" tooltip when you hover over the translation). This is yet another integration of Google Translate in Google's services, after translating Google Reader subscriptions and YouTube's search results. What other services would you like to integrate machine translation?
Google Friend Connect, the service that lets you add social features to a site without writing any code, is now available to everyone. Users don't need to setup a special account for a new site: they can log in using an existing account from Google, Yahoo, AOL or using an OpenID. They can also import a profile and the list of friends from a social network, but the only options are Google Talk, orkut and LinkedIn.
Google provides some basic gadgets that allow users to interact with a site: the members gadget that lists some of the people who joined the site, the wall gadget that lets you post general comments about the site and the review gadget, which associates the comments with an item from site (a blog post, a video). Friend Connect also supports OpenSocial gadgets, but there's no official directory of gadgets.
Google's new service is not yet a good way to build a community because it doesn't integrate with a site. You can only customize the appearance of a gadget, but you can't integrate your existing commenting system with Friend Connect or gain access to in-depth stats about your members.
You need to upload two files for RPC relay and canvas view, which is not always possible if you use a hosted blog service. Fortunately, Blogger already has the two files, so it's even easier to setup Friend Connect.
I added the members gadget and the wall, where you can post comments and links to YouTube videos:
Here's a short video that explains how to use Friend Connect:
