I think most people follow trends of popularity, but for communicating with friends and family I would stick to whatever works best instead of the most corwded network.
Absolutely. No people = no traffic!
I think aslong as the people I want to keep in touch with stay in it I dont mind if it goes down in popularity.
It depends on the amount of traffic leaving. If it was a lot, then yes, but if it was a minimal amount or a small portion, no. Facebook will not go down in one day, one week or one month, it'll gradually start falling. When that happens, I can't say, but it will happen one day I'm sure.
I only use social media for business mostly so I would definitely leave.
If social media went down to nearly no one else was around, then yeah I'd leave, but I would probably stick around for the time being. Once it becomes a barren wasteland I'm out.
I use it for work and for socializing. So-no, I wouldn't. I would keep in touch with family and friends there but find new place for business.
