Why not? If some posters decide to increase the entertainment or information value of their posts for readers, how is that a bad thing? Do you see information and entertainment as conflicting values? Is that the root of disagreement here about a Thanks button?
Having spent a lot of time in the Delta forum, I tend to have a negative view of trying to increase the entertainment value of their posts. I could link a lot of posts that I think reflected badly on Flyertalk as a whole. I like our sense of community but I don't want Flyertalk to turn into a cliquish place with everyone trying to one up each other on being funny and getting likes. I want this to stay a place where we talk about miles/points/travel etc. and focus most on that.
