* DevCoin goes 90% to developers
* GroupCoin is another charity coin where 50% goes to developers
* Tenebrix was heavily premined and seems abandoned
* GeistGold was just an experiment and seems to have been abandoned
I suppose if constant coin creation is an attractive quality in a coin, it remains to be proved. I think it should have other attractive qualities, such as greater CPU efficiency or something, to differentiate itself, not just the fairness aspect.
However, I think it is useful to develop the theory of such coins in order to lay the groundwork for other, more successful coins of the future.
Be clear that DeVCoin goes to artists, designers, developers, musicians, authors, engineers and so on of free open source things; simply saying "developers" might lead people to think that means the developers of the coin itself, rather than to people working on free open source projects in general.
GRouPcoin is not a charity coin at all, it is plain old 50 coins per block, 100% for the miner who mines the block, forever.
Tenebrix apparently will address the pre-mined arguments when it officially re-launches, possibly even by simply destroying any coins that were pre-mined.
GeistGeld, like BBQcoin but for a much longer span of time, has been a haven for CPU miners for a long long time. It is unlikely to go away any more than BBQcoin did.
