I overlooked MintCoin in the first week of its release and started mining in the second week.
If nothing else this coin will make for an excellent proof-of-work experiment, although I can see MintCoin being quite valuable in the future.
A large ongoing proof-of-stake percentage of this coin should really be given away to as many people as possible via social media.
If MintCoin is to act as a true currency then its distribution must be increased. Without increased distribution held coins will have a more limited value and its economy could stagnate not long after the proof-of-work phase is completed.
Early adopters and miners of this coin need to recognize that in terms of total future money supply they are perhaps holding the equivalent of a central bank or small / medium sized nation state in the long-term.
I ran a distribution model and the forecast for MintCoin is looking really rather good if many initial holders were to donate / giveaway around half of their staked coin profit to new potential users i.e. at least 50% of the 20% (in the 1st year) onwards ... So, 10% or less (or more!) or whatever you can afford.
The wider population both understands and likes to get interest on their 'money', especially 'high' fixed rates of interest that
is guaranteed. Thus, putting a few MintCoins into the hands of as many people as possible is going to create good demand. People will be saying: "Yes. MintCoin works and 20% (even 5%) is a better rate of interest than my bank on my money. I think I'll buy myself some MintCoin!" , "Got to speculate to accumulate"... etc.
The energy saving feature is also obviously a good selling point.
A wide free distribution of around 20 to 200 coins per. person is probably about the right amount. This could decrease against the PoS reward over time i.e. 15 to 150 in the second year etc. This coin (and others like it) could bring a really bright future for crypto-currency in general.
Alms to the crypto-poor - give and you shall receive ! 
P.S. If said giveaway's do not happen freely then everyone will probably be left holding a big 'bankster' style bag of worthless 'nothings'.
Hint: If your wallet balance looks 'obscene' - think about giving away some of your MintCoins. They will be worth more that way. Probably.
