I wonder if those citing 2 ads are actually scrolling thru the lists at all, because most of the time, I only see 1 or 0 ads on the screen at a given time:

1) In Forum view, both ads I see are scrollable, one a the top of the thread list, one at the bottom. I don't mind this implementation, although both ads are exactly the same, which seems pointless.

2) In Thread view, one ad at the top of the post list is scrollable and a second at the bottom of the page is fixed. I like this implementation less because of the real estate the fixed ad takes up, and having exactly the same ad makes even less sense here.

If I had my choice, I'd suggest putting one scrollable ad at the top of both lists and getting rid of the second ad, especially since it's the same anyways.

I don't have a problem a priori with ads - someone has to pay for the development of the app. I would also pay for a paid app, but the bar for functionality would be considerably higher to make it worthwhile.
