I'm thinking about making one, because I need a lot of trinkets in order to get the stuff want (Treasure Chest items, mainly)

So - to the people who have made them... do you get a good amount back?

Sure. It might take a while to catch up on all the dances you get (especially if you go to sleep and get up the next day), but you get a good amount of trinkets from it.

So far, I've found it to be decently profitable. Whenever I'm gone from my computer for a few hours I usually return to 10+ invitations. However, as more people began making billboards that number has decreased somewhat. I would still recommend making a billboard though because it gives a quick and easy way to make fast trinkets overnight.

Absolutely. I had a 10k billboard in my vault (which those are going for 2m right now), that's about 90 trinkets if you use the sP to buy trinkets instead. I know I've gotten well over 90 trinkets from people clicking my billboard, and it's still going too!
