No i won't switch yet because there isn't yet any credible alternative to existing social media sites.

Steemit is the leader (yes I have seen publish0x but it is nowhere near as good) but it is plagued by:

1) primarily the early distribution went to a few whales who would only upvote their own friends and countrymen. Basically, everyone writes there to try to grab whales' attention. Owners of Steemit destroyed it before they could even develop it further.

2) also it needs some moderation, the categories are awful.

Honestly, it would not be difficult to make a competitor that could dominate the market.
