Avid Pinterest users, prepare for some changes to your pinboards. Today the content-sharing site, which allows users to "pin" photos, videos, articles, graphics and other objects to their own boards, announced some slight changes to the design of the site and some new discoverability features.

Don't worry: the redesign, which the site started testing with users in January, isn't a drastic change. Or at least it won't require the same adjustment as Facebook News Feed. The site still has the big photos laid out in a grid (they are even bigger now), but along the top of your homescreen is a new navigation bar. A new button in the top left, next to the search bar, gives you a list of categories, including Animals, Art, and Design.

There are also some changes to the pin pages. When you look at a pin, you will now see other pins from that board (no need to click back), other pins from that source, and similar things to the that pin. The idea is that you'll stay on the site longer and continue to pin and repin items.

Pinterest has become one of the most popular social networks, albeit behind Facebook and Twitter. In November 2012, it was reported that the service had more than 40 million users. The site has become especially popular with women. According to a Pew Internet and American Life survey, 12 percent of online adults use Pinterest and one fifth of women on the Internet use the social pinning site.

The new design and discoverability features will start rolling out to all Pinterest users today. Just remember to put those baby or engagement pins on private boards if you don't want anyone to know your news just yet.
