I hope this can be of assistance to anyone out there trying to drive traffic to AdSense sites and others... We've recently (just hours ago) launched http://500googlewords.com and announced it privately on our mailing list (small membership). We'll follow this week with some more improvements but basically this feeds on the 500words.com trend, only providing access to what we feel will be a) a more effectively indexed site due to intelligent word groupings and b) one available to AdSense promoters at a MUCH lower price (500words and other clones drive you up over $200 per word in a heartbeat). Again, we just wanted to get the site out there and give people a chance to start buying words (many have sold already, but plenty are still there). As we make improvements over the next week we welcome suggestions, etc. Thanks.
