Happy 10th birthday Facebook! You have such a love and hate relationship with more than a billion people around the world. Awesome.

You guys wanna check out "A Look Back" [0]. It shows your highlights and moments in Facebook. It feels good reminiscing those moments. I wonder though, did they generate the look back videos for all of their users? I think that will require massive computation power.

My "Lookback" was beautiful; brought back some memories. Made me realise how much my life changed in 6 years.

As for your question, they are not generating it for every user; my test account doesn't have it. It's a 5 years old account.

Interesting. Maybe they just generate it for the active users. You mention it was a tst account, so I assume it's not that active and not a lot of content.

Yeah, not much content; I delete almost every post since they are just dummy posts made with the API.

I just checked again and I know have that page on my test account but no video:

  Thank you, { firstname }

  10 years ago people started using Facebook to share their biggest moments. Here are some of yours.

And then just 6 photos, though that account has 7-8 photos anyway.

I now also get that paged after having deleted one of the photos that appeared in the video. I wonder if they will regenerate it.

I'm hoping they will regenerate it :/ I deleted one photo from a bachelorette party because the cake very inappropriate and for whatever reason they chose that damn photo to be featured.

ITs the same story with me, first I hit the link I was able to see the video.....later on its just disappeared,after waiting long and refreshing no result.

I enjoyed lookback a lot, although it didn't seem to do much besides randomly select posts (the statuses it selected were not my most liked, and half the photos were of other people).

Oh wow that was amazing! I wonder how they tackled that too

My (active) account only showed a few recent pictures.
