All the steemit frontends you use coincidentally are also located on a centralized server. ;) It's a misconception that it's entirely decentralized. The backend can be accessed outside and call the data up and post data to it. Steemit.com, Busy.org, d.tube, dlive, dmania, etc all are frontends that cost money for someone.
I'm also tempted to just leave the project on my local machine rather than posting it up to the web, that's a lot of cheddar to put forth to hosting.

does it HAVE to be that way?
why not make an APP for that?.
It's possible to develop a desktop application that interacts with the backend accordingly, but doing so would also require compiling for every OS requirement. 32bit and 64bit Windows. Linux. OS X. Then you'd also need to make apps for Android, iOS and Windows Phone, PalmOS.
Overall it's just a massive headache. Far simpler with far less overhead just to have a centralized script as a website people can hit up instead. Far more cost effective.
