I found different websites where I can share links from internet.
1. link shorteners
2. Link bookmarking
3. Social networks (Reddit, Voat, Linkgum, Tumblr, Twitter...)
My opinion is that link bookmarking websites and url shortener are better than social networks. Link bookmarking websites and url shorteners allow users to save links as private and organize them into folders and categories. Users create their folders, lists, bundles, categories... of links. Social networks like Reddit have have some categories, but the categories are moderated. It is happening that some links are not allowed to be shared on social networks. Sometimes, reasons are not clear. On one of forums, I read that Facebook doesn't allow users to share their own websites. I submitted links to some downloads on Toptopic and my links were removed. Sometimes, Twitter and Minds did not allow me to share shortened links.
