I just read your post and its the exact opposite of how I feel its going on here...
Maybe I'm still too new (under a month on here), or maybe I just am not doing something right....I have no idea either way, but I've only ever had a problem with my voting power once in regards to running out of power (and I was still at 80+%, can't remember if it was 82 or 84%), any way, it told me for two days that I couldn't up vote or resteem or even post to my blog for the entirety of those two days.
Thankfully by day three I was back to being able to do everything again and haven't had an issue since.
I think it must have been a glitch though in my case because many other users that I spoke with had less voting power percentage than I did and were still able to up vote, post and resteem.
Every single person that I've come across and "spoken" with on here has been very helpful and kind about sharing information and teaching this old gal how to do this blogging stuff.
I can't say that I'm amazing at it yet but I am hopefully getting a bit better at it each time I post an article or make a comment.
I think in the end steemit will surpass all of our expectations and has limitless potential.
I hope your future posts do well. God bless and take care. :D
I predict Steemit will take over the market, my worries are for the small fishes like me having troubles being noticed...
