Update: Pixable emailed a thoughtful and sincere apology (below) that I appreciated. From my point of view the difference with the LinkedIn prank was that you only saw it when you went to the site; they did not send out connection requests from J. R. R. Tolkien. Pixable's intentions where not malicious and taking the time to send the email to me shows great customer service.
Hi Dain, hope all is well.
I just saw your tweet about pixable's email.
I want to personally apologize for it. We sent out the e-mail to have it simply taken as a harmless prank, possibly getting you excited about the possibility of seeing Ashton's comment, and then to be later just taken to the best April Fools' photos of the day.
To be completely honest, were only inspired by LinkedIn's joke, and as fans of Ashton, we thought it'd be fun.
We never meant it to be misleading in a harmful way, and again, apologize for any trouble it may have caused you.
We've made some changes to the category in order for it to be 10X clearer this is an April Fool's joke. (You can see it at the previous link or at http://apps.facebook.com/pixable/category/60/)
If you have any further comments of feedback, please send it my way; we would really appreciate it.
Noah Slimak | Product Manager | Pixable Inc.Thank you for the email Noah.
