Well, this site does it all for you. You just add the "pin button" to your bookmark bar. When you are surfing and see an image you just love, you click the button and 'viola', the images are added to your pinterest page.
It keeps the link where you found it, so if you want to go back you can.
It is also a social networking site, which means you can see what other people like and search for ideas. You can follow your friends or people who inspire you.... and you can share your own!
It may sound confusing at first, but it is an amazing little site that you will spend WAAAAYYY to much time on.
Here is a screen capture of some of the people I follow... Their pins show up on my main board.
This is a screen capture of my pin-board. It is sparse and sad, but I just started it today. :)
Anyhow, the main site is pinterest.com
Once you sign up (if you need an invitation, I have a few... so let me know) then we can follow eachother....
my board is http://pinterest.com/adhblake/
So, there you go! I guess if I have another site addiction.... all of you should too!
