Forecast Internet in future 4 (Instant messaging, Social network etc. Guess only!)

Guess only!

Since the near future, most of internet user on the world will use phone to use internet in most of time.

A free user use service provider's some free service, such as: opening document on online storage, or opened photo in album, or website space (or cloud Application space)'s content, the data flow for anyother user visiting, will be limited (each day).
The drivers or website space (or cloud Application space)'s downloading speed will be limited for visitors and free user of the service providers. But the paid user on the service providers, can have full speed to download.

New changed:
On many service providers,the capacity of email, drivers, photo album, website space (or cloud Application space) and anyohter, whether free user or paid user, all of these service, the storage space (capacity) will be shared.

3 Many email service and cloud drive (online drive),will provide only a few capacity for free user. Such as: Microsoft outlook mail and OneDrive (Sky drive), Dropbox, Amazon Cloud Drive and etc.

4 Many cloud drive (online drive),if a non-logined guest, or a free user, downloading other user's sharing public documents,the downloading speed will be limited, even can't download large files from the cloud drive (online drive). Maybe except the senior users have been shared files, a non-logined guest or a free user can download it.

5 Free users on Google, or a non-logined guest, if watch Youtube video, maybe can watch less than 1 min each video.

--------------------------
