If it's going to increase revenue for the site and in turn keep it alive then all good IMO. Running sites this size aint exactly cheap. So long as we don't start seeing Amiga branded too picks been advertised then I cant see there been an issue.
actually it is cheap to run a low bandwidth site like this.
(100gb is not a lot).
advertisers would want to know visitor levels though and perhaps pay based on how many view the advert.
$333 a month is a lot of money otherwise.
