I agree, we don't need another Reddit, we just need to show that it is a better place for people to experience some of what Reddit gives people. Communities and stuff need to be active, especially smaller ones. A lot of gaming communities aren't active on here and would be greatly improved if the gaming scene had a place to go other than Reddit.
Gaming is normally what boosts a lot of communities, websites and projects on the internet to a bigger place and that could be a start for Lemmy / Mbin.
It's also the case of people don't look at spam and go 'lets try this random site that people are promoting'
