After a good start, ad revenue has dropped to almost nothing after I moved it to the forum. That is probably because only about 10% of the players even visit the forum.
So, my choices right now are to bring it back into the game, or remove it because it simply isn't worth it.
...Or wait a little while and see if more players get interested in the forum?
I strongly suspect, by the way, that there's a second reason revenue dropped way off: At first, people were like, "Hey, cool!", turned on ads, and clicked on a few so they could support you. Once they'd done that, though, the ads started to recede into the background, as ads tend to for most people online today.
