It's a solid project with clear goals and a lot of work done in multiple sub-projects under the name XDNA.
Every block reward has a 1% dev fee and 2% charity fee. Using XDNA helps gather funds for charity, investing in XDNA helps them reach more people and bigger organisations, getting involved, voting and donating helps them direct the funds to where to community wishes.
I find their project noble and transparent.
Their PoW phase will last 3 years (we're 5 months in already) and during this time they are focused on sharing the block rewards to as many more people as possible. Their first hashing algorithm was keccak but when ASICs/FPGAs were developed and a huge amount of the hash was produced by a single entity, they developed their own, new algorithm which they named HEX.
This is a multi-kernel algo with some important differences compared to x16r and other similar algorithms, with the goal being that even if an ASIC/FPGA miner is developed, it won't be much more effective than GPUs and therefore not worth developing such a miner.
It's also noteworthy to mention that after the PoW phase they'll start the PoS phase.
