Similar to how building a new Wal-mart kills off many small local businesses (pharmacies, markets, shoes stores...) in the area, I lament how reddit has nearly monopolized the topic-based conversation and discovery platform space.

I'm old, so my route there is roughly: Dial-up BBS's -> usenet -> various web forums -> slashdot -> fark -> digg -> reddit. So I've experience the best and the worst of it all, and I'm not sure that reddit represents the best. I do not believe that they wield their [immense] power in a responsible or trustworthy manner.

I'm very curious to see what comes after reddit.
