I saw the blog now briefly, the content mix is great, all trendy stuff like sports, music artists, awards etc. The content is a bit to the short side, example the Roger Federer one and you can tell English isn't the first language of the author.
Still, Roger Federer is still one of the greatest out there. His record speaks of it.
I would have said
Still, Roger Federer is still one of the greatest players out there; his record speaks for itself.
I would encourage people to also write in their home language as it creates SEO for Steem in those languages and will bring wider demographics to Steem.
Maybe there is a free grammar checker that @iyalipol12 could use?
