Very true, a lot of minnows have complained about it. They are changing the threshold to 125 SP, but even so, not everyone has $250 to throw at an internet experiment, and it's not that easy to make 125 SP for a newbie in today's competitive blogging environment.
Thanks for the input. Yes, I noticed many of my favourite human curators fall in the 50-100 votes range. I bet you would vote more and on comments if you didn't have to worry about vote power.
As a minnow I believe minnows should not worry about the voting power. On my first day, when I know nothing about curation, I simply vote whatever I like. Then, I discovered my VP was very low and I learned that I can get paid by upvoting other people. Now I know some tips to increase curation rewards. But even I apply all these tips, I can only get $0.001 for each upvote on average. Therefore, I won't worry about the rewards, just upvote whatever I like.
