Nostalgia has gone viral.

Facebook rolled out a feature called 鈥淔acebook Look Back鈥� to celebrate the site鈥檚 10th聽anniversary. Facebook Look Back is a 62-second video that creates a montage of your most notable moments shared on Facebook, set to inspirational music, capped with a thank you message from Facebook for using the site. Though Facebook newsfeeds were almost as full of people complaining about the pervasiveness of the feature as users' minute-long videos, early reports indicate this could actually become a more permanent feature of 贵补肠别产辞辞办鈥檚 website.

Here鈥檚 how it works. Get the Look Back link ( or through any of your Facebook friends鈥� videos) and your video will automatically pop up. The video takes you through the highlights of your existence on Facebook from your first few uploads to particularly notable updates (likely measured by likes, shares, and/or comments), and ends with a signature 鈥榯humbs up鈥� icon, signed from 鈥淢ark and the Facebook team鈥�.

, for example, includes pictures of his undergraduate days at Harvard, his characteristic Adidas sandals, and the Facebook status update celebrating the site鈥檚 10th聽birthday.

The quick-hit reminiscing rapidly spread on Facebook over the past few days, and as with any viral content, drew as much complaining as sharing. Users took to Facebook and Twitter to complain of Look Back-saturated newsfeeds. Huffington Post Tech blogger Alexis Kleinman 鈥淣obody Wants To See Your Facebook Look Back Video鈥� that garnered more than 9,000 Facebook shares by Thursday morning.

The post also inspired joke videos, such as 聽parody video that chronicles some of Mr. Ford鈥檚 most cringeworthy moments, and the Orlando Sentinel鈥檚 ascension to football royalty (and subsequent fall) would look like through the Look Back video.

Look Back also brought up an unexpected debate about the service: what rights do family members have over a deceased relative鈥檚 social media content?

John Berlin of St. Louis, Mo., 聽to YouTube聽on February 5 asking Facebook if he could see his deceased son鈥檚 Look Back video. Though his son died two years ago, he had been unable to access the account despite talking with people from Facebook, he says, and he asked the site if he could put one together for his son.

贵补肠别产辞辞办鈥檚 only living members of Facebook are able to access their accounts, unless there is written documentation and instructions for the account from the deceased person. Though after a verification process, family members can request the account be taken down.

However, Facebook found out about Mr. Berlin's request, and that Facebook put together his son鈥檚 video Wednesday night.

Though a minute-long video may not seem to warrant this much hullabaloo, it looks as if Facebook may actually make this a more permanent part of its service. As of Thursday morning, section, that included instructions for putting the video together, as well as editing the video (though as of Thursday, the edit feature was not yet functioning). that the feature will be available soon.

鈥淲e will be launching an Edit feature soon that will allow people to change moments in their movies or update the ones they shared," says a Facebook representative. "I don鈥檛 have exact timing at the moment, but this will enable people to remove a post from the movie that was pre-selected and change it to a different one.鈥�

So if you don鈥檛 think Facebook accurately summed up your social media experience, you can tweak it to show off your best online moments.

Facebook also uses this 鈥淟ook Back鈥� help tab to demonstrate its privacy policies, which have morphed over the past year to encourage more individual control over the publicity of each post.聽

"Keep in mind that if your movie includes things you only shared with a few people, the people you share your movie with will now be able to see everything you included in your movie," says the site. "You can聽edit your movie聽to adjust what鈥檚 included, and聽select the audience聽you share it with. If you change your mind about who you would like to share your movie with, you can change the audience from your聽activity log."
