Yeah, i think its a good thing. In fact, Steemit is bringing back perpetual edits, or so i hear. Which will allow people to edit their posts and keep them relevant. Perhaps they could make comments to upvote as well.
I also wanted to tell you not to worry about the value of your vote. That will come with time. Until then, be frivolous with both your upvotes and your comments. Most of the authors here crave the interaction with humans, and your ability to provide that interaction is on par with any whale out there.
