WRONG. I was wrong A) because Pinterest is not just for people who like to cook and craft and B) it is a handy tool in more than one way. What eventually won me over to Pinterest was the fact that I could promote my blog through my account (not aggressively, mind you - Pinterest is not primarily for advertising). My first board was Geek Gear, which I used to remember geeky objects and art that I thought were adorable so I could share them with fellow geeks and blog about them - bringing attention to the artist - if I felt compelled to.
Here's the thing about Pinterest: it lets you collect to your heart's content. As a geek who has collected everything from little figurines like the one Dwight admires in Season 7: Episode 2 of "The Office" to "Lord of the Rings" memorabilia to books to shoes, I have finally come to see the value in a tool that lets you collect without crowding yourself out of your own living space, or crowding humanity off of this planet. As we all know, most Americans have a lot of stuff. We like stuff. Is it bad that Pinterest potentially contributes to this habit of gathering stuff? I don't think so. Pinterest is less like a bulletin board and more like a communal brainstorm that the internet will remember forever so you can always go back and see what you brainstormed. Pinterest helps me run a geek blog, be a more interesting cook, and plan a fictitious Shire-themed wedding so I don't actually have to become contractually linked to another human being. I kid! I kid! :) I would actually like to have a Shire-themed wedding someday (don't steal my idea...).
If I can find so many uses for Pinterest, I think anyone can. It doesn't hurt to check it out, and it doesn't hurt to go crazy, either. :)
