1) Of course, a vote is not required. Since it is a Karma issue. However, we tend to get feedback from the community before decisions are made. (This is not to say that the community has control over decision-making. it is the same as any other coin, except we usually ask for feedback.)
2) All ideas are welcome. Of course. We don't want to kill babies

3) no response, as it wouldn't be productive
4) I would argue that they're looking for legitimate coins. Karma(coin) was their second coin, and actually the coin that put Mintpal on the map. We're also legitimate, and would want them to know that we're serious about our success and actually have plans for ourselves. It could be said that we'd want to fortify our relationship further by working with Mintpal on changes that could possibly help us both. Mintpal needs volume (and transaction fees). It's possible that Karma could once again be their top coin.
We don't know which are good ideas and which are not. That's why we discuss, debate, explore, and sometime impkement.
I would say let's bring all ideas to the table and discuss them, as adults with goals tend to do. We can explore which of those may possibly be good but of course we won't know until well after an idea is implemented, if ever.
You are welcome to bring more of your own ideas to the table, of course. The more detail, the better.
When people have ideas I usually ask something like, "That sounds interesting. When can you start working on it?" I'd say that 95% fall silent because they don't actually want to do anything; just talk. Talking is good but it doesn't do the work.
1) I meant that the community has no say in how an independent entity such as an exchange conducts its business and nor should they expect to.
2) I agree...
4) I would argue that Mintpal lost its volume because it got hacked and then colluded with coin devs to save its (and their) asses. We can be thankful that they did that because we may every well have lost many coins if they went under, but at the very least we should be aware of the ramifications. Trust in mintpal (and all exchanges for that matter) has been broken and it takes time for that trust to come back. This is at the core of the issue and I don't think that pushing mintpal to make changes just to benefit any particular coin will do much good considering how much pressure they are already under just to stay alive.. but by all means suggest it to them if you think its worth it. Personally though I think it would make arbitrage extremely difficult to have prices listed one way on one exchange and listed a completely different way on another exchange and arbitrage is what irons out the volatility and creates stability.
5) you welcome ideas that's great... I have been offering ideas since the second week of this coins life.. selling lil and reinvesting the money would be great, establishing a stability fund that actively trades Karm to reduce the impact price volatility would be great, creating a portal the way VRC does that allows anyone to spend Karma on any bitcoin accepted site would be great. the continuous charity work which is being done by members of the community is great. Porting the counter party protocol onto karma (ala doge party) would be great.
To have an idea and be willing to take responsibility for its success or failure is something to be commended. It's also a sign of maturity.
I agree and i would like to see this happen more often. Also I would add that looking at the success and failures of other coins and learning from them is also a sign of maturity.
