I started making a mobile (.mobi) version of the Community Color directories. Mobi are super scaled down sites for cell phones.
I think mobile will be big in the local entertainment scene as people want to connect with events, venues and restaurants while on the go.
Salt Lake is the community with the most events; so I will use it as a sample. To go mobile, I made a page for the calendar, venues and events. I also started making a directory of mobile sites.
My basic idea at this point is that if you have a mobile site, I will list it in the MOBI section of the main directory, then display all of the items for the MOBI page on the cell phone page.
The first interation of the .mobi stuff is now live. .mobi sites look boring ... but I think it will be useful. The real challenge will come in trying to figure out how to advertise the existence of the mobi pages, and figuring out how to monetize the program.
