Well, if you're asking for opinions, I'll offer a few. I certainly appreciate having another option for focused tech aggregation, especially if the comments section is able to attract and retain high quality, well-informed commenters rather than redditors.

Stylistically, I think there's way too much white space on the front page. HN has spoiled me.

And if it's supposed to be a HW site that attracts good commenters, there's way, way too much intro level material on the top list right now. I was getting turned off by the several intro to FPGA links but intro to soldering made me close the page. Not that introductory material can't be there, but there is a very low cool stuff to introductory material ratio.

I like the idea a lot, and wish you luck. Hopefully I find it again in a few years and love it and eat my words.
