I have tested Zurker for a while now. Even that the fact is, that it is still in beta, I like what I see. Zurker works as a middleway between Twitter, Google+ and Facebook. Zurker has two timelines, one for your own activities, and one for all your friends, and the people you follows (you can subscribe, without making them your friend).
You can share everything at Zurker: News, blogs, links, photos, updates, and much more. People are discusing social medias, networking, business, and about anything else.
You can sort your contacts in selfdefined categories like family, collegues, followers, and you name it. The members of Zurker is adult people, because you have to be 18 years to be a member.
In beta, it is not possible to join without a invitation link. It is free to join now, and it will be free forever...just like any other social media.
If you like to give it a try, you can use this invitation link:
