I have! And boy do I LOVE Pinterest now!
It's all about organizing those randomly found wonder ideas out on the internet and bringing them home to a VISUAL bookmarking organizational method. It really is simple and it really does WORK!
You do a simple download and add their toolbar to your top of your browsers regular basic toolbar. Once you have it there, you can travel the internet and whenever you find a wonderful idea, sketch, artwork, or whatever--you can then pin it and it will go to your own boards. The PIN IT button will make a bookmark style notation electronically so you can at any time after that go straight to your boards and find that idea BY PICTURE! No more trying to remember whose blog something was at. Its all visual. Sort ALL your crafts, sketches, scrapping or other tutorials, ideas, even your own work into boards on your Pinterest page.
Anything you need to keep track of online, Pinterest will help you keep track of where it's at. After you have pinned a photo, it's on your board for you to come back to at any time. From your board, you just click on that photo of the item you want to go see. The photo gets larger and then you simply click again at the upper right where you see their URL link. Poof away you go back to that page that you want. Browsing the internet is so much more fun when I know I can actually keep track of those cool ideas and online tutorials!
Just be sure that when you are looking at a bookmark PIN for the first time that you are actually pinning to the base link for that idea and not just a picture of a picture. Follow up to find the actual web page the idea came from originally. Not just someone's compilation of links. For those of us who have original ideas and tutorials out there, it is the only way to make sure we still get credit as a creator. Keep the original author's link as the PINNED link.
Pinterest is the ultimate "What You See is What You Get" bookmarking application for those us who are in a hurry. I am very visual --and frankly I forget to bookmark websites the old fashioned way. You can check out what other members-- who have the same interests --have pinned to their boards with the Pinterest keyword search feature. Do you love decorating with blue Ball jars? Type it in at Pinterest's home page search engine and see what others have pinned. RePin the ones you like from other people's boards over to your own boards. Love making chocolates? Make a whole board of delicious photo links to those scrumptious treats! You'll never loose a online recipe again! You could theoretically make a whole online virtual cookbook via Pinterest! You can have as many boards as you like!
Give Pinterest visual bookmarking a try. You can start with my own personal boards here at PINTEREST. I suggest the board called "Inspiring Crafty Stuff". Have fun!
