Hey man, you may already know this, but just in case; when you post in a community, the post doesn't appear in your blog page. If you would like it to, you can just reblog the post yourself, from "all posts" and it will appear in your blog too. This is handy if someone checks out your page, and they think you haven't posted in 10 days. Not everyone knows to also check the 'all posts" page.
Peace.
