Depends on what you do. I use feedly and never even visit reddit. I can get the top ten posts from any sub delivered to me daily. For example, i've done some group buys on limited keycaps sets and doubled and tripled my money on em selling em 6 months later. The mechanical keyboard sub hasn't been like that in many years as there is so much more variety now. It's good for free advertising of your shit as well. edit: i also get also greentexts from the 4chan sub. what's best is most the time i can see the posts that were deleted as they were cached in the feed reader ensuring i see the funniest shit.
