Local Content means nothing without...

Delivery when and where it is relevant.  Lots of interesting initiatives are taking place now, but if you can only access local content from your house, or workplace, it does you no good when you're at the place that it's germane to, and that's the achilles heel of all these wonderful web 2.0 services.  They're only valuable when you're connected to them.  Right now, there's two mobile platforms that can make local content useful, and two networks to connect the content to the platform.  The former are the smartphone, and the laptop.   The latter are the cell data networks and wi-fi, in both hotspot and hotzone flavors.   As more dual-mode smartphones and wi-fi enabled mini-systems become available, that are not crippled by carriers like my Cingular E61 has been, relevant interactivity with local content will become more possible and popular.  The growth of public WLAN access, in whatever flavor will also drive this consumption, especially if presence applications make it easy to use multiple voice applications from a single device that has multiple radios ( both licensed and unlicensed or "open" spectrum )built into it.
