Proof of burn is _not_ about burning all the coins you get. Imagine if all miners would do this in a pure PoB coin - there would be no coins left to trade, for eCommerce etc. It would be not a coin but a casino-like game as you couldn't do anything with the coin than trying to "profit". So a good PoB algorithm should not make "burn-dem-all" profitable (game theory basics).
The purpose of PoB is to find an equilibrium when a significant amount of coins are burnt but not all, sufficient to make an attack expensive. Maybe 5% or 10% per month.
https://en.bitcoin.it/wiki/Proof_of_burn has some thoughts on it.
Now the forks are another issue, that should be resolved fast, I agree. But PoB is an completely new and experimental technology. I think the great problem of this coin is that it was added too fast to a major exchange (Bter). So there arrived people expecting to make profit, and are disappointed now. That's natural, but it doesn't mean "it's all over" now because of some forking problems and a small value.
I would really like to see a development community emerge for SLM or for the PoB technology as a whole, because I think it needs to be more than a one-man project and PoB has a lot of potential. (Unfortunately I'm not a developer, so I cannot help with the code, but I can do marketing and this kind of stuff.)
