I loved the way my burgeoning pin boards look cascading brightly down a browser page. And I enjoyed exploring other people’s boards, too, adding gems from their collections to my own. But the real rush came when people started commenting on, liking, and repinning my pins. One image I posted of some seafoam-colored roller skates elicited 13 likes and 56 repins.

It wasn’t long before I found myself constantly checking to see who had repinned, liked or commented on my posts. One afternoon, when the site refused to load, I got really impatient—I was pining for more pinning.

Despite its general addictiveness, some of Pinterest’s features are clunky and lacking. Pinning images, for example, requires several steps: First, you spot the item you want to pin—say, a sweet orange couch you noticed on a design blog. Then, you click “Pin It.” This creates an overlay filled with all the main photos contained on the page you were just looking at, and the images’ sizes. Click the one you want, and a smaller window pops up asking you to describe the image, categorize it, and pin it.

This should be simpler. In fact, a similar site, called Fancy, makes this same process a lot easier: When a user clicks the “Fancy it” button on the browser’s bookmarks bar, a little popup window lets users scroll through the page’s images and select one. Or, you can just mouse over images directly on the website you were browsing and click to choose the one you want.

Pinterest could also use some other functions, like the ability to create private boards or to rearrange items on a board simply by dragging them around on the browser page. And it would be nice if it could suggest people for me to follow based on our common pinning habits.

Overall, though, Pinterest makes it fairly easy to curate all sorts of images I come across in my online travels. If you can snag an invite, it’s definitely a site worth getting stuck on.
