I am under the same bandwidth restrictions as everybody else, so would love to reply to everybody individually but am doing so with an eye on my remaining bandwidth.

Votes and comments are low-bandwidth activities, but if you are posting an article, cut down on the huge images and videos as those will cost you! Words are cheap. ;-)
Resteeming also cheap I suppose? Only with voting, commenting and resteeming I was through my bandwidth with an hour or so. Might have embedded a couple of YouTube videos in some of my comments, 1 or 2 per session that was limited to an hour by the bug.
