Is this an idea or did this already happen? I could not find the answer in your post.
I assume its an idea and I respond to the idea:
I think its a great idea. I support that it is forever, and not limited in anyway. It would boost the "implementation of blockchain and steemit in the world". I like the idea 100%, not need to adjust it in anyway.
I will add that the referral bonus should include people signing up directly after viewing a persons post. Meaning that if some person see my post and choose to signup from that post, I would get the referral bonus forever.
Steem on!
