I'd resteem A LOT more if:
a. I could have a separate tab just for resteems - this could be useful for "saving" posts too which I want to do but can't currently
b. If I truly believe it helped so much. Unfortunately, I feel that a lot of people don't really read. This is bound to change in the future!
How much?
if 1 happens, as much as I want to!!
There is a feature for saving posts if you use the busy.org interface.
