I can reply your question. There's some community on steemit that are really active, those communities are : cryptomonney, photography, food and life-style essentially. introduceyourself is also a very active tag but it's different.
There's also some tags like your country tag that are very useful. For example, i'm a french cosplayer and photographer. So i always tag my article wit hthose 3 tags : cosplay photography fr. I haven't a lot of comments too, the post where i received most of my comments are in my introduceyourself post !
Something bad with steemit is that, even if you follow someone, if you don't check regulary their blog, you couldn't see anything from them. So the only advice i can tell you is to keep it up, one day maybe you'll get repost !
