The Google +1 feature is more or less a bookmarking feature. It reminds me of the old del.icio.us website where people were able to bookmark websites and that was it. There was no tagging, no sharing, and not a whole lot of social features.
What I enjoy the most about the +1 feature is that it is simple and easy to use and you don’t need to organize it or use tags for that matter. Links that you like are there, and it is as simple as that.
The +1 feature enables you to see how popular it is by seeing how many people +1’ed it.
So, how do I +1 links and pages around the web? Simple, I use the Chrome Extension +1 button found here: https://chrome.google.com/webstore/detail/kmonhedbcpagbphilnoajiencllnpoii
To view other people’s +1 links click their profile and see their +1 tab!
