I may be wrong here . But given a choice of desktop application like Windows Live Writer(yeh windows only); many people would face a question? how does it matter using new web service? In most of the cases I wont be pushing the same content to multiple blogs at once. Sending mail is the simplest solution one can see though. Friendfeed-mailFF and now posterous. Also jason calacanis's shifting from blogging to email platform. its all 360 degree cycle. Are we redefining how to blog ( by mailing either through posterous/way jason calacanis done having exclusive mailing list)? oops everything is getting redefined
