Except that the only ones that have made improvements are LTC and PPC, all others are just copies to get rich quick
Who cares...? That's my point.
If you don't like a coin, don't use that coin, lol... It's that easy...
Sitting on a single blockchain and spitting on every other blockchain you've never been on makes no sense.
You check them out, compare the clients, compare the mining experience, compare the spending/receiving experience and decide whether you like it better than what you are already using, if not, then delete it and STFU about it.
I use and mine on a few different clients for different reasons. I like some because they have faster confirmation times, I like another because the client has chat and other GUI features I enjoy, some I mine simply to test different mining settings because they have a lower difficulty or more rapid block time.
Just about everything can contain value to someone even if it doesn't contain any value to you, you are not the deciding factor of what matters and what doesn't matter. Should the grocery store stop carrying a food just because YOU don't want to eat it...?
If you don't like a coin, don't use it. Sitting around being dramatic and bitching about it isn't going to do anything but get you trolled.
