Just tried Google Helpouts

It's like an updated version of the old Google Answers thing. Live video chat. They let you try a free one with just a Google employee (presumably mostly asking about the service). The guy said it's about 3 weeks old, and they're still making lots of changes.

I did a search for some house stuff and didn't get results for most (installing the Nest thermostat, how to know how to clean your wood floor), though there was an interior designer who'd help with where/how to hang my pictures (but at $20 for 15 minutes, I'm not up for trying it).
