To be totally honest, I'm surprised it's taken this long.<p><i>Everyone</i> knew a year ago when they were acquihired that Posterous would be discontinued. Why do I say this? Well, Twitter's bread and butter is in 140 characters, if they wanted to look at branching out into micro-blogging they wouldn't need to acquire a company, of whom the majority of their customers already use Twitter. (It was borderline a zero-value gain for Twitter if you take out Posterous' talent)<p>As it stands now, Tumblr clearly won (Although there has been a few emerging startups of insignificant size. Soup.io is one that springs to mind that is currently in an accelerator). If you are looking for hosted solutions for your startup's blog (or you are at all technical), I'd <i>genuinely</i> think about using GitHub. Start to pull your posts from Posterous and use a static content generator. Jekyll / Punch / Middleman / Hyde / Korma / nanonc / Frank + (any of the other 10 static generators)..<p>The operative point from using services that generate static content is that you are <i>always</i> in control of your plain-text content. Just push your new post and GitHub will handle your site. If you are worried about traffic on your site or extended build periods (I believe GH does rate limit static sites, and as a comment below mentions, on infrequent occasions builds can take upwards of several hours) then you can still use any other solution... Push to Amazon S3 and proxy through Cloudfront, then you will have probably one of the fastest, geographically distributed blogs on the internet.<p>This was always happening... Especially when you consider that for the last 12 months I haven't seen a single new feature since they were acquired. I've logged in, see the same "Posterous has been acquired" header for the last 12 months.<p>Move on, and safeguard your future content.
