I think the simple rule of thumb is to try to show at least /some/ bit of professionalism. Many alt coins are flat out cancer to alt currency in my eyes. People will see all the stupid ones and think that's all alt coins are, a huge joke ran by little children. I scroll down the topics and see a Dubstep coin..which is utterly absurd in every single way. A try-hard cat version of Dogecoin launching that takes the worst of lolcats and vomits it all over the place. Even the ones that try to be taken seriously, I just can't...like how Earthcoin literally looks like someone lifted the "e" from Internet Explorer.
Of the many alt coins out, only a small handful feel legit. BBQcoin..Anoncoin..Sexcoin..the whole lot needs to go away and make room for people who take this seriously.
