Professional Identity

When setting up my professional twitter account I knew there were a few things to keep in mind. The most important things being:
1- Anyone can see everything that is being posted under my name. Being a teacher you should expect for students to look you up on social media and it is important to always remember this.
2- Make sure that your picture and background make you look professional. There is nothing worse than looking unprofessional and how do you expect to get a job when you look that way?
3- Keep everything updated and stay current with technology and other posts about education/teaching. How can you be respected as a teacher if you aren't up to date?
