For those obsessed with one visual theme.
A picture sharing website or collection of websites, where users can browse and upload their pictures in various themes (only windows, only phone booths, only glasses, etc.)
Keep track and possibly show your collection of stamps.
An online app, where you can upload photos of your stamps (singly or a page at a time.) The app will recognize the stamps and create an online catalog of your collection.
Create a never-ending list of stories.
An app where you enter you airplane code and your seat number, and you can then do two things: read all the stories of people who sat there before you on other flights, and add your own. Each seat on each plane has an unlimited number of stories you can browse on a timeline. Stories about the people who sat there, about their flight, unrelated personal stories, any kind of personal story.
A score card for restaurants and the likes, from the people who matter – neighbors who give their patronage.
A website and app where you can rate restaurants around your neighborhood. This will help new neighbors, people visiting, and the restaurants can use it in their advertising.
Most people who collect never achieve a large or exceptionally valuable collection.
Have a website where people can show their private – even small – collection. Be it a collection of blue bottles, stamps, or art. The size or value does not matter. People can browse the pictures of their collections, and it can also function as a marketplace for buying and selling collections.
