I'm just curious as to what your numbers are and if all forums suffer from this ad blindness.
Often I search for something (usually a "how to" something) and a forum such as this one shows up in the results because one of the regulars posted the information I was looking for.
In other words, getting your forum posts indexed and ranked will increase your CTR. The problem is most, if not all, forums suffer from issues such as duplicate content (multiple url's accessing the same post) that may prevent decent rankings for the content of your forum. Your site may get ranked well, creating an opportunity for more regulars and repeat visits, but the actual content in the forum may not be ranked good, meaning only the regulars see it.
Just my 2 cents.
