Ask HN: Forums Similar to Hacker News in the Internet

I was not able to find anything close to Hacker News at least UI-wise, moderation, comments and content-wise.

The anything closer, imo, is Reddit and Slashdot.

Do you have any advice for the best way to get an invite to the site? Great content on it

Not sure what you mean by similar. tildes.net is similar in some ways.

Can you spare an invite?
