Great post! I agree, the only features that even seem worth implementing into steemit would be pm's/wallet transfer and some form of credit/debit card integration(to make spending easier). An online marketplace would also be cool. But seriously, who the hell wants ads? I read they also take a portion of your sale in commissions when/if you do sell something. I don't think steemit should be worried at all, just keep making improvements and adding features that make the end users' experience more enjoyable. Take what works from other platforms and leave out the stuff that doesn't.
