TechFuga is a new site that tries to breathe new life into this space. It's an aggregator of tech news aggregators: simply put, it takes all of the aforementioned sites and many others, plus a bunch of tech blogs, and brings all that together on one page that's eerily similar to Techmeme, with some news sources being chosen as primary and others as related news.
I have now seen enough similar sites to say the following: if you want to do this right, you need to have an editor, who's going to manually sift through the stuff spewed out by an algorithm and sort out the important stuff from the not-so-important stuff. TechFuga doesn't seem to do that: they combine the popurls approach, which means simply stacking a lot of RSS feeds on a page, with a Techmeme-like algorithm that chooses Top Stories.
The result is solid, but a bit too messy for my taste: there's simply too much stuff going on here. If I'm going to go over all these news items, I might as well simply check out what's new in my Google Reader. The Top News part of the site, on the other hand, is virtually identical as Techmeme, only less readable. So, the question is, does the world really needs a popurls meets Techmeme? It can't hurt, but I don't think it's essential.
