The beauty of steemit in regards with app development, is that it is open for anyone to participate - @ausbitbank made tools for the platform he would personally find use and value in, and I guess the community felt the same :)

There is so much room for growth and development of the platform, and it is brilliant to have general users be able build things that will benefit the community at large - the developers do some truly amazing work with their creations.

Cheers for the feedback :)
