Trying to introduce scarcity by heavily reducing the block reward will not do any favours long term. Outside this will be seen as an act of greed and unfair to new investors after the block reduction, it would in no doubt give advantage to those who got in before the block reward reduction. All that would do is scare investors away long term.

The plan put forward is a sane one and will see a reduction in coin supply over the long term by sticking to the more conventional inflation model put forward by Bitcoin. A reward halving at 1.5m blocks is within the first year. Artificially trying to reduce the coin supply outside of a well thought inflation model will only see a short term benefit if that. Those who are interested in the long term survival of Talkcoin will appreciate the plan put forward by the Talkcoin team which is made up of the most prominent members of Talkcoin. There are no better people to look after Talkcoin's well being and those who have been following Talkcoin will be very familiar with them.

I believe that the changes happening now are Talkcoin's best chances of longevity.
