So I’m leaving Plaxo, thanks to Aral and others for notifying me about this screwup. I was probably going to leave anyways, because Plaxo is being acquired by Comcast – and I’ve had plenty of issues with Comcast (just have not posted them yet, ha).
I went to Plaxo help, and of the Top 25 articles, how to delete my account was #1!
So, unless you really, really love Plaxo and don’t mind them sharing your email address with the entire world, then I would go delete your account.
Update: Plaxo has a history of screwups.
