Remember, early votes are worth lot more than late votes. Most blog posts you encounter are already heavily voted

I was referring to seeking out posts to vote early versus betting on comments which don't even receive an upvote 50% of the time. I haven't done the precise computation, but I can't imagine it ever pays to focus on curation rewards from comments because they most often receive 0 votes and those which have more than 1 vote are rare and even rarer are ones upvoted by whale. The odds for comments have to orders-of-magnitude worse than seeking out blogs.
