We're running ads on these forums for approximately 30 days, to estimate how much revenue we might earn from displaying those ads over time.
We're trying to find out whether ad revenue might be enough for us to avoid some price increases in the future, while still continuing to add new features and improve the ones we've got.
At the end of the test, we'll post an analysis of how much everyone's subscription cost would change if ads were running. Using that, we can have a discussion about whether the ads are worth the hassle. My personal opinion is that ads would have to substantially reduce everyone's subscription costs, just to be considered. We need to run the experiment to make a fact-based decision.
Lots of folks - me included - happily pay $1 to avoid ads in their favorite mobile devices. That also might be an option here. If you have other ideas that would accomplish the same thing, please reply.
In the meantime, if these ads are entirely unbearable, and you're able to install ad-blocking software, I really like Adblock Plus.
