WTF with the ads in the first post on a thread?

I assume what I'm talking about will be to the right of what I am typing now. I understand these sites are ad-driven, and I thank Stangnet for being here for us, but seriously, I hope this is an error in the HTML code for the page or something and that SN isn't seriously letting the ads intrude right into the posts....

Now it's not doing it. must have been an error in the code or something, but it was weird and aggravating. Mods, feel free to delete this thread and keep up the good work
