I am not sure if you found a way to find your blog posts. But, here you go:

Click on your "Profile" icon on the top right. Select "Write a blog post". From the left side menu, select "All posts". This will show all your blog posts with status.

But, I think this is not very intuitive. Instead of "Write a blog post", it could just say "Blogs" so we know that will lead us to "Blogs" page.

Yes, I second your opinion. In the new SCN, I have to wait for someone to answer my question to get a notification or search through thousands and thousands of them.

It would make much sense to have a menu option that says 'Questions you asked' that will get all the questions I asked in one click.
