Short but not snappy :)) I like your header and sub-header. My stab at a sub-header would be...
A place where one can publish anything, connect with anyone and enjoy the incredible content of a rapidly growing, diverse and global community. You're engagement will earn you money and reputation...have fun!
Something like that.....it's very similar to your effort and i'm still not entirely happy with mine either....it's dam tricky!!
it is tricky! I like what you've came up with. Anything but welcome to the blockchain is a major improvement in my opinion.
