I have noticed that the site has become quite a bit slower than when I first posted here. Possibly because of the ads- not sure. Maybe we need more pipe.
But without your user base- who are basically filling this site with the content needed to bring even more users and provide reason for ad purchasers - you wouldn't have a site at all. I am sure you are aware of this. I have seen plenty of sites crash and burn because of unusability created by ad revenue.
It's a fine line..
