I'd answer your question of the value of PAL and WEED:
the value of the token is equal the attention you get from those communities. Perhaps somebody is running a weed business and want to get attention on the WEED platform. Then you need to acquire some WEED tokens. On PAL you can even promote certain posts and the payed PAL will be burned (reduction of supply).
So the formula more or less = [Active community (attention) / amount of tokens] this will drive the price and value in my opinion.
