I guess what I mean by “too much” is that I run the risk of losing people’s interest by overdoing it. It’s not too much for me. I could post 15 links a day if I didn’t think it would annoy people and if it wouldn’t encourage people to do more post promo. For me a link to someone’s music or a video (especially playable within the webpage/app), which I think is cool, is not the same as post promo (which I very much dislike)
