S60 s screen size and iftnreace doesn't really lend itself to a usable blogging app. I tried all the available ones on my N95.Furthermore, it's harder to develop for S60 (imo) and there are lots of different S60 devices out there, with varying screen sizes and keyboard setups.On the iPhone, you've got a single form factor, a consistent screen, which is big enough to fit enough on to be usable, and fairly rapid development if you're up to speed with the tools. Oh, and a large rabid foundation of users.
