Welcome on board! Now that's a great discovery story XD

As you've probably noticed by now there's also multiple front-ends of which steemit is only the first (there's also Partiko and eSteem if you want mobile, SteemPeak and busy if you want nicer catchall and things like palnet and creativecoin if you want more specific interest stuff, just to add a bit more confusion to chaos ;D

There will be people around to ask for help if you're curious or stuck :)
