As some people have posted, steemit isn't really a social media site, it is a blogging/commenting site.

I would totally put a very well written Blog about my business on Steemit.
It is free, and is a free link back, and it is great for clarity and presence.

Steemit is not good for people to find you. The search features are not what they need to be for a blog system yet, let alone a customer interaction system.
Too many blogs already disappear into the black abyss without ever being seen.

Steem could be exchanged directly for goods, as long as you do not mind the lack of trace and fulfilment features. There is no customer support pieces in place, or deemed to be in place on the developers calendars. Adding a customer feedback, again, is not even on the radar.

So, I would make a great blog about each of your products, just to have its presence on the interwebs.
