There's datatau.com for data science.

I think the tendency is that independent attempts die off.

well, now. this is interesting. I love data science and data viz. thanks!

Does anyone know one for hacking on cars? Everything from stereos to Rpi touschscreens to Speeduinos etc? Just after a place for all sorts of modding car electronics. I've been going it alone for a while now but would be keen to bounce things off like-minded people. I'm on a few big car forums but they're generally based around performance and mechanical modding, with electronics being a tiny subforum or afterthought.

For designers

https://www.webdesignernews.com/

thanks for sharing.

I wish designernews was more active, really like the site though.

for webdesignernews, I don’t really think it qualifies since a central entity decides what is news and what is not. It’s more like a news blog. It also doesn’t seem as though users can comment on the links, but I could be wrong about that. I’d put it in the same category as a site like sidebar.io. What makes sites like HN interesting is that the users publish and the users decide what’s newsworthy... for better or worse.
