Everyone screams about ultra-low banner CTR and the need to offer context-sensitive, targeted advertising. Every now and again, something comes along to remind me that good banners
still work. Example:
Bonzi [bonzi.com] is running a banner on my sites which hawks voice email (yuccch!). My sites have zero to do with technology, software, hardware, etc. (except that they use it to run and my traffic uses it to get there). Still, this company's banner is consistently pulling in 6%+ CTR!
