A Replacement for Metafilter?

I've decided that it may be time for a replacement for Metafilter. I still enjoy the core element of Metafilter which involves bringing up interesting things from the net and discussing them. However, the people on Metafilter have gotten too old, bitter and cynical for me. I don't want to hear another grumpy poster ranting about everything wrong with pop music over the last two decades, and that no music has been good since the 1970s. Reading Metafilter these days just makes me depressed and grumpy myself, and I don't need that sort of crap.

So basically, it's time to hold tryouts for a meta-site like Metafilter, but more cheerful and enthusiastic about life and the internet. Any suggestions?
