I deleted my http://geekli.st account after the way they treated Shanley Kane (http://storify.com/charlesarthur/oh-hai-sexism).
Even though they issued an apology and a clear PR exercise of devoting months to 'Women in Tech' it couldn't change the attitude displayed by Christian Sanz and Reuben Katz.
Will I regret my decision to delete my account? Maybe. Thankfully there are other alternatives out there like http://coderwall.com.
