My understanding of Martin's comments is, essentially, he believes the ideas system needs more exposure. 66 positive votes whilst a good thing, isn't even a fractional percentage of users that are involved with phpBB.
In order to properly move towards community-driven software, more people need to be taking part and that can't happen unless the ideas system is properly endorsed and marketed.
Endorsement: A publicly documented criteria of: When an idea becomes 'popular' , when it would be 'up for discussion' , and potentially guarantees that a certain feature would be implemented into the core once it reaches x% of approval with a minimum of x votes.
Marketing: 3 key locations. phpBB Homepage, phpBB forum index and phpBB ACP. Ideas system needs to be implemented in these areas to maximise exposure, encourage community ideas and increase the votes so that a proper consensus can be established.
