It's not going to show up popular websites much because CS research, like most research, is not a popular topic. But if you want to know what's going on, a great place to start is to start reading the proceedings of recent ACM conferences: http://portal.acm.org/browse_dl.cfm?linked=1&part=series...

Yes, it's behind a pay-wall. Not much I can do about that [1]. And yes, you will have to read academic papers. But that's where people talk about real computer science.

[1] Although, if you find a title and abstract that sounds interesting, you can usually just Google for the title and find a copy on the author's site. All of my papers, for instance, are also on my webpage. And, yes, this is explicitly allowed by the copyright transfer agreement.

In some specific areas (like mine: graphics and vision), there are compiled lists of recent papers from the best conferences, along with links to the papers, project pages, etc.:

I have been a member of ACM for the last 2 years, but just let my membership lapse. Their site is nearly useless for anyone who is not already at least an advanced undergraduate in CS or IT. The parent post is looking for resources for learning CS, not advanced study (or so I understood it).

http://lambda-the-ultimate.org/ is worth a look!

When you find a really good site on HN, add it to your RSS reader. Check out proggit. If you have an industry you're interested in or a problem you're trying to solve, start googling and keep track of all the interesting sites you come across. There's a wealth of good stuff out there, though it isn't going to be TC style (linkbait titles, unnecessarily effusive prose, etc).
