I run two reddits where self promotion is okay, assuming it's relevant to the problem space and not excessively often. One is r/ClothingStartups. You don't have to be selling clothing for it to be okay to pop in and ask for feedback on your product. You do need to be able to make a reasonable assertion that you think it could be pertinent to early stage, small clothing businesses. The other is r/GigWorks. If you are working on a gig platform of some sort, you are welcome to pop in there and talk to folks. R/ClothingStartups has a few thousand members and regular traffic. People actually get feedback there sometimes on the stuff they are trying to do (mostly clothing businesses). It's growing at around 40 to 60 members per week with little to no promotion.
