@jacobtothe, I don't have an issue with upvoting original posts, especially when someone is posting quality original content. As for voting power, my rule of thumb is that if it's good/important enough that I'd resteem it, it's good enough for a 100% upvote. The rest of the time, somewhere between 10-50%... which works well with the amount of time I can give to curation on an average day.
Comments? Mostly 5-20% upvotes, unless I feel something said really deserves a boost. Or I am trying to vault it past other stuff to greater visibility.
