The article makes it sound a big deal to develop J2ME app. This app basically has just 2 screens, so I wouldn't think it would be any big deal to replicate those screens across platforms. Their challenge is more on the server-side, scaling for all the billions of users that they have - again, no big deal for plain text but mostly the pictures and the videos that are shared ...few big datacenters somewhere...again, nothing great. And hey, they dont even support voice calls. I dont buy that the app itself is a deal breaker. It's mostly their user base that they have been paid for.
