Sounds interesting. Curious to see if the idea actually turns into a real thing or will remain just as a project idea someone else might take over.
@OP what I wonder is, will customers at least be able to purchase this beer using BTC or will it be all about the name?
30 posts per week, I guess that's too high for a payment of $ 25, I suggest you decrease the post requirement and hire more posters, that way it could minimize the spam it could possibly make. I'm just saying based on my observation in the past, most signature campaigns now have only 25 post maximum per week, some even have pay per post and a minimum of 10 post while 25 is the maximum to get paid.
I wouldn't say it's that big of an issue, there are enough users that'd join the campaign for that payment amount. Pay per post is interesting but gives a more variable advertisement result.
