Many top coins now can be considered as "nothing special" but they were first. Now, you can't just clone them, you have to do something new. You know how much clones of Monero and Dash exists? For what reason except to make their creators richer? Well, I also like idea behind STRJ because "mining" on HDD storage service. But I don't know, maybe this idea already used before. Anyway STRJ listed on Poloniex and quite succefull last time I checked.
