Hah. I'll just copypaste a comment I left elsewhere a few minutes ago:
Because it still pays me something.
Although I've found a platform that rewards me more and I've been focusing more on that one. Also, I'm holding on to some naive hope that maybe a new whale comes along and notices me and adds me on his autovote list.
So I'll post here and there.
Also, beneficiaries is one of the few good and worthwhile features here.
Actually, SteemPeak is just a front end on the Steem blockchain. You don't lose any of that.
I know. But then again, I only use the site steemit.com for vomiting my content on the chain in hopes to whore myself for a few bucks, so the UI doesn't really matter much.
