Whats the scope?

Just read the blog today and this seems interesting and congrats to Raghu for starting this.  

Saw some of the ideas posted here and firstly what I wanted to ask is,  what kind of users are going be the targets here? The regular PC users or mobile users or both? As we know, we are going to see some sweeping changes in the way mobiles phones are gonna be used in the next few years especially with the 4G network which Sprint is going to introduce soon in an year or so. And speaking about mobile technology, how about the idea of developing apps for iphones and pdas? Also,  mobile gaming is something which is becoming a universal craze day by day and is here to stay for long.  The gaming industry is only getting bigger and bigger. What do you think guys?
