How far are you willing to go to defend this? There's been lots of technical talk in this thread so far, but I'm curious on this portion.
So far I'm LOVING the UI. I actually think you should drop the payment part ASAP and just push for more users in the standard social media format.
I also think a staggered release of new "tags" is a fantastic idea, but needs to scale ASAP (until the site is ready for users to create their own hashtags/subreddits)
EDIT: After using this more, it's so exciting and fun to see something so new and fresh. It really feels like I'm back in 2010.
I still have pressures however. Using Stripe and credit cards for payment processing means I have to ensure the sites primary purpose isn’t adult content, as if that content dominates its very likely Stripe will choose to no longer do business with me. I can still support it, but it can’t be the primary purpose.
