I don't understand this Pinterest website at all. It's totally useless. But millions are using it.
In my days we sent emails to share things and that was good enough. We didn't need those facebook and twitter and pinterest thingies.
Oh how I wish it was the year 2002 and I would be 25 again. Everything was easier at that time. And slower. For example Google would only update every few weeks. Everything is so fast nowadays. Suddenly I feel so old.
