My post appears for me if I go to my profile page and switch the view to "most recent posts." I am not sure why it only wants to show one post of mine at a time though; this seems pretty confusing.
ETA: when I go to Chris_Leong's page, it doesn't show him as having written any blog posts at all, even though he has clearly written a blog post which I am currently commenting on. So perhaps there is some deeper problem?
I thought that instead of everyone having to create a separate post for their first impressions, it would be more convenient to create a single post for this discussion. I'll post my own here soon.
