Most of the social networks are about advertising, groups and pages and stuff like that, i miss the old times when Facebook was about sharing news and activities with friends. Today i can barely see what my friends say because timeline is filled with advertised posts, group posts, suggested pages, and so one, and so one. And im not even interested in that.
Someone could make a social network where it would look like facebook in old times. Maybe with groups, but mostly about uncensored timeline where ALL statuses and activities such as likes, comments on posts, etc will be displayed.
Of course there can be ads to get money for paying for servers but just somewhere in the sidebar so that the timeline is simply for users.
