So, just like many people, I thought steemit.com was an actual April Fools Joke, when it came to be on 1st April. Then i buried my head in the sand because I'm a massively butthurt BitShares hodler, and I figured it represented competition. Now it is slowly dawning on me that Steemit is awesome, and you should all check it out - but be careful not to lose your password once you link it to your FB. And stay buying BitShares.
I got locked out ish somehow yesterday, but managed to recover, somehow. My sign-up was some kind of error, - it never happened but the site kept insisting that my account was already signed up. I deleted website history for a completely unrelated, non-pornographic reason (honestly) since then, and managed to get my FB linked to my preferred user name. Delightful.
Also, it seems possible to sign up to steemit.com without FB.
