Social media sites like Facebook and Twitter have become hugely popular. Millions use blogs and microblogs like Twitter to share their views on various topics. While social media allows users to stay connected with friends and voice opinions, it also presents some drawbacks. Nothing shared online is truly private, and people can form fake identities. Users should be aware that commercial entities and governments may access their personal information agreed to through terms of service. Overall, social media allows connections but users must be careful about oversharing private details online.
