I often see this tactic on X (where you can create and host your Live Space) + on YouTube. I think that the very first time I saw it when @_maxblade was streaming. Then more and more people started doing it. IMO, it is a good tactic when you have a powerful fanbase/community on a certain platform. Do you think it is a "strong invitation" to participate in upvoting? What other (unusual) tactics can help?
