If you need to sell steem quickly, how can you sell? Blocktrades.us seems to be disabled until pre-orders are filled?

Blocktrades is working absolutely fine. What currency pair you see disabled on blocktrades? You can also go for Openledger exchange.

Was there a fork recently?
It seems I have way more payouts on my recent articles.

There was no fork, just that Steem and SBD prices have increased very much and hence the payout rewards have also increased a lot.
