Strange thing happened to me yesterday. Posted a new entry. All went well, except the post does not show up on the main page.
I can see the post if I know the post URL, I can see it under the Category into which it is posted and i can see it in the Archieves.
The post's header is just numbers: "2011", could this somehow prevent if from showing?
This is the post: http://www.the3inchcanvas.org/2010/12/2011/
Wordpress version is 3.0.1
