JU is acting Hinky today {GASP} .  Yes it is true.  Many have been posting 2, 3 or more times because they get an error when posting an article.  It happens, it has happened before, and probably will again.

Just a suggestion for those not wanting the hassle of multiple articles saying the exact same thing.  When you get the error message, open a second browser window (leave the original one on the Article you are trying to post) and navigate to Joe User/Newest Articles.  If it is listed, just close the first window.

Make sure you open a new window.  This is for 2 reasons.  If the first window really did not post, you can always hit "submit" again (after hitting the back button).  Second, by opening a new window and navigating to the Newest article page, you ensure you will get a refresh of that page, and not a cached copy (which the latter could lead you to think it did not take the first time).

Just a trick of the trade I figured out after having to clean up several burps of my articles as well.
