It’s fine. Just remember that it is your Profile page and it represents your experience. It’s a great place to capture something that you learned or figured out or a decision that you made. I think of threads in terms of what is going on now; in the short term. Things to think about or questions to ask or just interacting with other members. The Profile page can be used to document your history, what changed for you, etc. There is no right or wrong as long as it reflects you.
