Here’s an easy way to post from Google Buzz to Twitter and Facebook. They should really build this in, but until they do, here are the steps.

First, find your Google profile. In Google Buzz, you can click here to get there:

Once you’re on your Google profile page, which in my case is http://www.google.com/profiles/petervandijck (because I set it up to have a friendly URL, but it could also contain a bunch of numbers), you need to look in the code to find an RSS feed of your Google Buzz posts. This is a little geeky, but easy enough, the Google docs explain where to find this feed (they should really make it easier to find!). In your browser, look for “View Source”. In Firefox, view source in the menus looks like this:

In the source, you can find the RSS feed that publishes your posts in Google buzz. It looks like this http://buzz.googleapis.com/feeds/113278766329192120580/public/posted (that’s my feed), and here’s a screenshot of where to find it:

OK. Now you have a public RSS feed with content (from your Google Buzz). From now on it’s easy – there are many ways to get RSS feeds published into Twitter or Facebook. One great way that you can use for both services is Twitterfeed, just go sign up and point your feed to Twitter and Facebook. And you’re done, your posts will now (with a short delay of half an hour or so) be crossposted to Facebook and Twitter.

Google should really make this easier though.
