Hi @valth, thank you for your feedback.

There are some implementation complications with allowing answers to be provided as main posts or comments which would need to be resolved.
Not impossible but with flexibility comes more testing and work when new features are added.

Remember that our preference is for people to use the StemQ UI when contributing answers, rather than blogging Steem apps like Steemit or Steempeak.

StemQ makes it very easy to answer a question. It's just a matter of clicking the "Answer this question" button really.
So in that respect, it's not any harder than commenting.

As I explained in the post, the issues are that comments don't really get curated by @curie, @steemstem, etc.
Also, nobody would notice a comment on a question post that is several weeks old.

But of course, one is free to provide a short answer through a comment as well.
It's just that it wouldn't be treated as an standalone, browsable, answer by StemQ.

Thanks again.
