We've covered Posterous here on multipleÂ occasions simply because it's an awesome blogging service. Setting up your new blog is as simple as sending an email. Â It's simple to set up, simple to maintain, and free without being overburdened with ads. Just recently, however, one user noticed something fishy going on. Posterous was converting links to affiliate links without any prior notification or consent. This particular user was able to see what was going on because of a minor glitch on how the affiliate links were being generated.
The primary issue here is that Posterous did not notify users of the potential changes (they have only been testing the feature so far). Full disclosure and transparency have become pretty standard, so this being accidentally discovered by a user looks kind of shady. Posterous cofounder Sachin Agarwal has since posted an apology regarding the matter. The integration with VigLink actually began in December of 2009 on an experimental basis. There are also a few points to note:
Links in Posterous posts are not edited in any way
Copying links is unchanged
Publishers can opt-out specific links my including a rel="noskim" attribute with an option coming to omit entire pages
There is no breaking of the web, redirecting, or other trickery that might have an adverse effect on your page rankings with Google. VigLink is backed by Google Ventures, after all. (VigLink statement)
Some users are upset that Posterous would do something without notification, or that Posterous is monetizing using affiliate links, or even that Posterous is changing anything period. The bottom line is that Posterous isn't doing anything all that serious here except to neglect notifying users of what they were doing and potentially tenting their perception of transparency.
