I think that everyone reposts each others posts and images because they take an interest in the the same thing that the poster does. Maybe you share the same love for a certain movie or think the same quotes are inspiring. Sometimes when you circulate posts by reblogging them you can show someone something new that they’ve never seen before. There are a lot of things that go on in our community, in the world, and on the internet and posting and reblogging things helps to inform others of the current events and interests in the world. The new fashions and new saying and happenings spread and people are more informed about things that other people will be talking about.
