Why all the fuss? Well, obviously this means that a much larger number of handsets around the world will have mobile access to a wide selection of mobile applications. RIM and WinMo phones make up the vast majority of handsets in the corporate world, and although the corporate world doesn’t revolve on having a wide range of apps for various tasks, it does mean this: all those business users who, for whatever reason, haven’t adopted handsets like the iPhone that already have apps stores, they will now have the access to apps they will want to use in their personal time.

And aside from those users that have chosen to sport two phones, one for professional use and one for personal use, most folks prefer to pack only one phone on a day to day basis. So most folks will now be able to download mobile apps to whatever phone they’re tied to.

Again, for many of you, so what? Application stores mean that users have access to a wide array of social applications; beyond that, developers compete aggressively to produce the most intuitive and powerful applications every day, and to offer them at the best price points. Right now there are certainly aren’t enough applications for the most popular social platforms, but we’re going in the right direction. With the added stores for Blackberry and Windows Mobile, even more developers will be drawn to projects for mobile platforms. I can almost taste the quality to come.

Also, one of my biggest problems with the nature of mobile social networking to date was that social media really can’t be mobile until every phone is able to partake in the community. Until now, that wasn’t possible; when you rule out Blackberrys and Windows Mobile phones, you’re left with just a piece of the pie. Now we can at least say that we’re at the right staging point from which developers can now start working on truly intuitive cross-platform apps that allow everyone to connect, regardless of their carrier or handset.

This is big. Get excited.
