If it was a public open network then maybe, I wouldn't use it to share things between friends though or messaging. Could be based around posting of public events like a billboard/invitation feature (the tool i use most on fb), and maybe a twitter like status feature too. I wouldn't share images unless random gifs and memes or anything too personal/controversial. It wouldn't be a full network more like a public information service. There was talk of bbc doing something like that.
