What are the most useful subreddits you have tried ?

I use Reddit a lot and there aren’t really any subs that are particularly helpful for promoting your product. You can find some great resources there and decent feedback (if the cynics don’t gang up on you lol). In terms of brand awareness the culture of Reddit is pretty against it. Many people use it as a hobby site and will not be helpful if they believe a company is trying to exploit their interests for profit. It’s really hit or miss though.
