So we can officially say internet became way too centralized.
Gallery? Use Instagram.
Communication? Only Facebook.
Microblog? Twitter.
Videos? YouTube.
Search engine? Google.
If any of these sites will be shut down, there will be problem for current internet users. They will need to set up new service. And R.I.P. these data. Try to use multiple services for this. You will lose only part if it will get shut down. At least Wikipedia won something once.
If they shut down it wouldn't be much of a problem at least for me.
Instagram? Okay a bunch of photos, I don't care
Facebook? Okay, I can communicate outside
Twitter - Just a bunch of short thoughts
Youtube - Well, this one I will miss a lot. Very useful thing
Google - That's a huge problem as well. It would be harder to find information. Though we have Yahoo, Bing, DuckDuckGo, etc.
So we will be alright anyway
