OP is saying "please don't go into the business of shoving ads at me when the reason I'm following you is because you have interesting things to say."

OP is channeling the average user telling you that if you do this you will be unfollowed.

I'm not sure I agree with OP, it depends on the topic. The HN crowd is not indicative of the general public.

For example, the fashion people would probably be happy to see curated ads.

Buzzfeed's sponsored ads are pretty good for the Buzzfeed audience. I agree on the point yes, content links can be posted over and over as people get enojyment from them, posting products will soon lead to unfollowing, is why I'd like to find a good niche and something people want and build a community.
