This is an open discussion topic. Discuss whatever you want.
If you post a link, express an opinion about it, ask a question, say something. Also, if you think something is bad and are posting it for criticism, say so – the default expectation is you agree with, and have a positive opinion of, whatever you post. Or if it seems good to you but you're sharing it because you have doubts and want to find out if people have criticism, say that.

FYI, I also have an email discussion forum which is active (703 posts in the last month). Posting there requires learning how to do plain text email quoting correctly.
Unsure what to discuss? Ask a question. Read some of my writing and comment or criticize. Try my book recommendations and try to analyze what you read and share your notes. Or share some of your life goals, learning goals, or problems you'd like help with, or share anything you think is important.
If you'd like your own discussion, with your name on it, please ask and I'll make a new post for you.
