Google announced they are working on a social networking website called Google+ which is going to compete with Facebook. It looks very promising so I look forward to test it when they release the website to the public. I especially like the idea of creating "Circles" of people to share things with only some groups of friends, not everyone. I don't want to express my political and other views to everyone or, on the other hand, bother all my friends with information about programming that are understandable and interesting to only those who share my passion.
Facebook is already popular, but we all know that Google develops good products (like search engine, Gmail, Chrome, Translate and numerous other stuff) so all in all I hope Google+ will become the successor of Facecbook, not a big failure like Google Wave. I already publish my photos on Picasa not on Facebook.
