I don't think I have ever clicked a topspot banner on this site. I find them more annoying than anything with their stupid sounds and music.
I actually find the "spam" posts to be more informative, and I actually click them more. For instance I checked out that new Plugin that was on here today...
topspot banners are pointless to me. Branding falls into that same category. I can think of much better things to do with that money.
