We should think about the advertising model before its too late and it gets shoved onto us. I think each community should get its own advertiser and they get a stick post on each post which is limited to 300 chars and one url.
Its simple, non intrusive and we can make it a bidding. 80 % of the proceeds should go to the maintenance of the instance, 20 % should go to the moderators of the instance.
Would warner brothers want this for 100 $ on movies ? I think so ..
Right now we don't have the appropriate amount of users. Even if lemmy gains users, it would have to collect lot of personal data, no advertiser would want to advertise on low CPM
