Some people think that social networks are not worth it because a lot of people vote for their friends. Some say there is no good content. Your content can get buried. Some say your content gets buried by the readers, and some say it is buried by employees. You may never reach the front page. Well, a lot of people say different things. Everybody does not experience the same thing.
I only use social networks so that my content can be found. While writing for Triond, I sometimes find it to be the best social network. I am right at home. If people don't like my content, it is still online unless I delete it. Buried or not, sometimes people still find your stuff on the internet. It all depends on what a person is looking for. There is no need of worrying your whole life through about all of the things that seem unfair.
Keep on moving and find better ways for you. Spend less time worrying. Maybe social networks are not for your content. Having a website and a blog might be the best place and your greatest fans may have found you through one of the search engines. Who knows? Search engines, social networks, and directories are all important for content. A person should never rely on one thing anyway. Don't put all of your eggs in one basket.
