Posterous lets you post multiple photos, video, music, all through email. Autopost to twitter via email. Best Mobile Startup Finalist, Crunchies 2008
I've been using posterous since 2009 ...not only makes for enjoyable blogging, they upgrade without redesigning their already 'quality' platform, no need for constant 're-learning' curves. Awesome tool; the mobile usability is fantastic, the toolbar bookmarklet is easy, "SlideShow for Pages" presents your images beautifully ...can't say say enough, this is one of those solid sites.
