Like HN is the best community for hackers, which sites are there for designer community, where the designers showcase their work and discuss about design related topics?
DocType is the most useful for me; DesignFloat tends to be pretty random/useless sometimes since it's an aggregator and the links it has don't always directly pertain to design.
This doesn't directly answer your question, but I wish more design related topics would show up on Hacker News — benefits hackers who are looking to learn more about design, and it's a really good startup related topic anyways.
If you're looking for places to share your work and get feedback, then http://dribbble.com and http://forrst.com are your best bet, although both are currently invite only.
The closest analogue I can think of is Undrln: http://www.undrln.com but it doesn't get anywhere near as much traffic as it did a couple of years ago, unfortunately.

Also there's DocType (http://doctype.com/) which is a Stack Exchange style site for designers.
The Web Design subreddit gets some activity too (http://www.reddit.com/r/webdesign).

http://forrst.com is invite-only and caters to both designers and developers, but it fits the bill.

If you're looking for more of a link dump type thing, then http://www.designfloat.com and http://www.uberlook.com (my site) might have what you need.
