We've just enabled IntelliTXT in the forums; it was previously only working on the main site. We've been very happy with the results of IntelliTXT so far, as it's already generating some significant revenue for the site (though less than the pop ups and such), which has my brain racing for ideas to use that money in 2006 to make the site better for everyone.
I'm not sure how well it will work in the forums, if at all. It's a rather different audience from the smorgasbord of people who read the main part of the site. As we tweak the settings over the next week or two to determine how many links will show up per thread, which pages are excluded, etc., we'll also be seeing whether there's any increase in the click-through rate. In other words: would forum posters actually click the green links? I don't know, so we're going to find out.
I'm sensitive to the fact that inserting these contextual ad links in YOUR forum posts is different than putting them in OUR editorial content on the main site. I don't know how you all will react. If you're like me, you've learned to ignore the green links, so it may not matter. Or maybe you're already incensed.
My point is that I'd appreciate your feedback on this matter (please be civil and thoughtful). Also, if your feelings on it change after living with it for a few days, I'd like to hear about that.
