Supporters of all these altcoins are clouded by bias and are missing the very core of something: redundancy.
In that I can make a perfect clone of *any* coin now, including Bitcoin, give it all the features, attributes, security, and issue rate of a great coin, even with no pre-mine, I can give the very same "immaculate conception" as Bitcoin, etc., etc.
So with all of that, should this altcoin I create just automatically be deemed as having value? Just because I launch it into existence? No.
What it has is redundancy. To Bitcoin.
If I create a new clone of Linux is it better than Linux? No, it's just redundant.
If I create a new clone of an iPhone is it better than Apple's iPhone? No, it's just redundant.
If I create a new clone of Facebook is it better than Facebook? No, it's just redundant.
And on and on and on... redundant things are worthless things. See the recent fate of Google+ as an example.
Although going overboard is possible with anything.
