They combine news with good in-depth analysis of services to show what exactly you might want to use them for – and in general this article is pretty good.
It does have one major, major, major omission, though, which is so obvious as to appear almost intentional.
When Jennifer Van Grive details the autoposting options Posterous offers, she writers:
‘a single Posterous video post could auto-post to Twitter, Facebook , YouTube and Vimeo and blog sites, while photo posts could automatically add images to your Flickr, Facebook, and Picasa accounts.’
What she doesn’t make clear is that Posterous will actually autopost to Tumblr.
That’s a major advantage to Posterous, and certainly a major element for discussion in a ‘head-to-head’ comparison.
