Social media sites provide networking platforms where we are free at any given time to post or send messages which reflect our thoughts, feelings, and intentions. I believe that we cannot be prejudiced and misjudged by anyone for posting online daily or almost everyday. Therefore, I personally think that it's all up to you. If you think and feel that you have relevant information to impart everyday or if you simply wish to express yourself freely without inflicting harm to other people, it doesn't matter how many times you post in a day or in a week. For example, if you're using social media sites to support your business, you'll have to update your status daily and expand your influence constantly. Likewise, if you have a more casual message to post, you can simply voice out your ideas through famous proverbs or describe little events in your life which mean a lot to you in between work hours or school hours. Having said that, you can either post on social media sites daily or almost everyday.
