I think way to many developers "cash out" the premine versus using it for development purposes.
I don't have a problem with premines because it's up to the miner if they want to invest time and money mining the coin. It's all about choice. As Cinn above stated, she doesn't like the premine, so she has made the choice to not mine the coin. Choices are good, we all can make them based on what we believe.
I have the feeling that a smart dev can always acquire a (hidden) early mining reward by using heavy mining gear (scrypt, sha256) or renting on f.e. amazon or even a botnet. The newest X-xx algo's that a few days after launch sometimes mysteriously get the possibility for GPU mining are also suspicious as an early miner could have a huge advantage.
Also a dev can play the sentiments as he or she ideally is in control of the news/hype flow.
A 0.1 or 1 % premine in many cases will be a small part of the dev's stash but of course the only undisputed part of it.
Of course a hit and run in scammy IPO style could get the developers some petty BTC short-term, but if they play it smart (anyone say drk?) they can be filthy rich mid-term.
Of course all the investors are looking for a mid-term / long-term opportunity to earn back manyfold their initial investment so the risks can be huge.
But of course you have been in alts longer than me so you might disagree or have something more profound to add which could be interesting!
