Boring....
Face it, Facebook is stagnant as it is. You've managed to get 1/4 of humanity to enter a lifetime's shite into your poxy online database of guff, where else is there to go? People are happy to see Auntie Ethel's new dog, their mates out on the razz or your workmate's new car and that's all they want (anti)social media for.
Install all the whizz bangs you like FB and your ilk, it won't make people sit up and listen any more.
Listen up Zuck...
THE SOCIAL MEDIA NOVELTY HAS WORN OFF. WE'RE BORED WITH IT NOW.
The first time you "hooked" up with youR brother in Oz it was neat, he shared piccies of the kids and the dog and it was novel. Now FB and Twitter are just like a toaster, useful but you could probably manage without it. The toaster simply toasts bread, that's all the toaster will ever do, "I toast, therefore I am." as Talkie Toaster said to Lister, the humble toaster can have all the AI and flashy lights but all it will ever be is a hot box that burns bread products. All social media is from now on is a just a medium to send naff messages and post naff pics, it will never, ever be interesting or exciting ever again.
