We need a place to discuss stuff like pixel density, new energy, and quantum computing.
Some of these things could be put into different forums (mobiles, PCs, etc.), but there is some merit to giving a centralized location for discussion new science and technological innovations.
Personally, I would like to see a science version of Nilay Patel on the Verge staff. Someone who doesn't just repeat the same science story the rest of the internet is echoing without understanding what is actually going on, but dives in and delivers a useful analysis to the readers.
