Most of the tokens I have no clue about at all. I ran into the SPI one, I am not sure how, and the concept behind it I liked, it is/was a slow growth plan, but as we both know plans do change. Then the SPI team started to expand and so far I have been pretty happy with how they work.

I do like some of the fun tokens like ENGAGE, BEER, PIZZA, what I see as vanity tokens, but they are a nice way to provide a little extra to people, as long as they don't have a big annoying self advertisement.
