It's incredibly hard to create an application that will update a blog to the high standard that many readers expect; partly because there are so many different blog hosts that are not quite compatible with each other in their back end; partly because the majority of blogs which are self-hosted (such as my own) will be ever so slightly different, but mostly because it's pretty complicated to format, edit, proof read and publish digital thoughts from a small mobile screen. Many have attempted it, and the latest contender, the open source Nokia Wordpress Client, is better than most.

Can you develop a single client that will work on every blog? Probably not, there are just too many variables; but you can make a client that hits a majority, which I think is the reason that this Qt-based client focuses just on Wordpress.
