Although Google+ was launched more than a month ago, many applications and services have been already built on it. Which is really amazing considering the fact that, Google+ still don't have a public API. So, I started the roundup with API hacks to understand how other apps might have been made of.
1. PlusFeed
![PlusFeed : Unofficial Google+ Users Feeds](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjYv2jaSFxxmzuRA0r__IqA33OhzYki3WPAyIhDe4dM8VRJaUvWbsj5YCBmlJdeyD87MS7s4uJKtj8iICN0VxeTqtAGeYf3G9La1vVzY8VOBWW_udUV__ECTVP29FFSOtZM3Vy28Razw3U/s800/Google-plusfeed.jpg)
The idea behind that app started by inspecting AJAX calls on Google+ page itself, which showed that Google uses this URL "https://plus.google.com/_/stream/getactivities/118211149935481259253/?sp=[1,2,"118211149935481259253",null,null,null,null,"social.google.com",[]]" to load your posts, which returns a malformed JSON array of my Google+ posts.
While you cann't use that malformed JSON in Javascript directly, you can use Google Feeds API to convert ATOM feed from PlusFeed into a regular JSON array that you can use.
A WordPress Plugin was already built based on PlusFeed. Also, The same idea was implemented in a PHP class by Rich Kreider.

A similar service can be found at plus.ly.
It is also interesting to note that the old public profile URLs like this "http://profiles.google.com/mikedotmore" now redirect to Google+ profile.
