Hello M!
I really enjoyed your post. I shared the similar thought with you regard to the social media. I consider it is a good platform to share interest thing from my life to everyone. I also agree with you about professional identity and personal identity. The real information is important to build my social image, which is very important to build professional identity. For the purpose of manage and protect my privacy, I also like to separate my personal and professional identity in different media, which is very helpful to me to mange well, and build a good social image for different purpose.
