Thanks for the feedback. I was surprised a bit by the interior design concept being a top candidate. Granted, small sample size, but interesting all the same.

Here's some pros to that idea:

- I've definitely have felt the need as my wife and I searched for some interior design advice in the past, even calling a local designer (who never returned our phone call.)

- being able to discuss and bounce ideas around with my wife could be nice as well

- would be interesting to get feedback from designers as well as prospective clients

I have no idea the market size, and I'm still unclear as to the best means of designing a room online, but putting together some wireframes or landing pages seems like a great way to start.

Thanks to everyone for feedback thus far!
