Know what not to blog about. Things like private information—both yours and other people's—and personal details that you don't want to share with people close to you shouldn't be topics for your blog. Also, controversial articles or posts may get you some temporary popularity but it also comes with cons like less safety and targeting.
- If you have a job that required you to sign an NDA (non-disclosure agreement), you should avoid discussing activities or topics outlined in the NDA.
- Blogging about other people is fine as long as you don't harass or discriminate against them, but be aware that they may see your content and retaliate.
