Hi @slavmys. Nice to see you on here, especially knowing you have your PhD to do, which must take up a lot of time. However, there will be loads of stuff you can use in it for great content, maybe not right now, but definitely later as you start to grow your account.
Also check out the #promo-steem posts, of which I'm part of the team. We are committed to helping new members and minnows get the support they deserve and to spread the wealth around Steemit.
