Man, this trend of creating social news/aggregator/HN-clones is really catching on! Not really a bad thing IMHO, and I probably feel so because I'm working on "Yet Another News Aggregator" for another particular niche. I think this is basically a trend of creating subreddit-like sites, except with more customizations allowed.
What differentiates this from, say, /r/games?
Just curious, because at a cursory glance it appears to be just Yet Another News Aggregator
