Tenebrix was premined, also the developer abandoned it along with the community.
Litecoin developers are still very much active- they are about to update the code to include all improvements up to Bitcoin v0.8.x
All the ALTs that copied off of Litecoin at its current state will be running Bitcoin v0.6.3 code. I hope these pump and dump developers are savvy enough to upgrade their coins like Litecoin is doing, otherwise eventually they will be left behind and forgotten (most of them are headed this way anyways.)
Also... create a better community? Bitcoin/Litecoin has a huge community, good luck trying to surpass all their development and services, etc. They are already ahead and have a bigger community to develop sites/services/updates to stay ahead in well into the future. There are also many more people invested into Bitcoin/Litecoin than any other crypto currency, so more people have incentive to make things and start projects because it increases value.
Why update the code? What purpose does it serve to "upgrade your coins"? Mind explaining for us newcomers to the community?
Before someone spouts off something about newbies - we are buyers too and compete for value.
Because the code on which all the cryptos are based is not bug free. And since most of the coins are a copy of either bitcoin or litecoin they will most likely contain the same bugs as found in bitcoin and litecoin.
Most of the devs of the 'new' coins have no clue how the whole of the system functions so they will need to follow the bug fixes from the coins with larger dev communities so their coin does not get destroyed by known vulnerabilities.
