I've only been Steeming for about a week but this seems like a fair critique.
I'm almost scared of posting "real" content as it will be ignored by comparison of post engagement. Additionally, with the limited tag amount it greatly limits specific overlaps in communities and fandoms. The combination really plays up a few elements I expected upon joining, exacerbating not just marketing yourself fully but makes content that cannot be immediately, easily (and in many cases forgettably) posted a wash or at least risky regardless of substance.
