Thank you so much for this post! I've been fighting the bandwidth issue this past week, being the worst when I come on first thing in the morning (about 13:00 UTC) and I couldn't work out why it would come back faster in the day (when I was on and chomping at the bit to post) rather than at night (when I wasn't on at all...)

points of discussion...
I guess it doesn't make sense for new users to have as much bandwidth as they want - though it also takes time to build a following, so allowances must be made. I want to post 4-5 times a day to build a repertoire and to keep interesting potential readers. That much should be okay without too much hassle, I think.

Yes, having users pay for additional bandwidth is a definite possibility - though that could also bias towards big companies coming in and taking over with their infomercials and other advertising.

Those are my thoughts, anyway.
