The shoe-maker's family has no shoes?
One trouble with being a consultant is getting time and energy for your own projects.
My wife and I spent a busy week or so a couple of years ago building a healthy cooking web portal. Since then, with just a few changes, the site has been running on auto-pilot. I wrote the original implementation in Java+JSPs, and now my wife and I are talking about investing more time into what is for us a fun hobby (we are both extremely good cooks).
Anyway, Carol and I have been talking enough about the recipes web portal that I think that we will start work on it again. We only have a few hundred registered users, but we get a fair number of visitors who do not create a free login, and an average of about 5 page views per site visit, so people hang around. I originally used the USDA nutrition database to estimate nutrition data for recipes - I took that off because the data seemed inaccurate (USDA often sites multiple studies that vary a lot!) However, enough people have asked for nutritional information that I will probably add it back in with a warning to accept nutrient data per recipe as estimated information. One thing that I implemented in the original site that people seldom use is a free custom database of "food ingredients on hand" - with a nice option to only show search results for recipes that you have the ingredients for. A good lesson here: sometimes users will ignore features that developers think are great! I might remove that entire module of code and web UI stuff - if users don't use something, toss it out.
