Tuesday evening, Pinterest rolled out some changes to its very popular website.
In the past, when you clicked on a pin, you were taken to a new page to view that pin. To go back to where you were to continue browsing, you had to use the Back button. That landed you back at the top of what could be a very long page, forcing you to find your way back to where you were. Users who learned to shortcut-key a link to a new tab had it easier, but it was still a pain in the butt.
Now, Pinterest uses a lightbox-style feature (a la Google Images) that simply overlays a smaller window, fading the main window into the background temporarily. You can re-pin, comment, like, Tweet, get embed code, etc. from there. Once you are done, simply click off to the side to close the lightbox and return to exactly where you left off.
Pinterest has also made it easier to see where an item was originally pinned from, no matter how many generations of re-pin have happened before it made its way to you. This allows you to find the original pinner, which is a great way to make new connections with people who are actively on the lookout for new content to pin, as opposed to serial re-pinners (not that there's anything wrong with that).
