I see that a couple of the ads I made up on a couple of the SE sites got past the threshold to be on the normal cycle.
But where do they show up? I thought it was on the main site (scifi.stackexchange.com) but I don't see any community ads at all.
And the only ad I see on gaming.se.com is to follow them on twitter.
Are they randomly shown to users? If so, then why doesn't constantly refreshing the window show any ads?
