First things first: You really earned to be out of bandwidth hell. I've seen you post really regularly and all of it quality posts! :)

Regarding the bandwidth increase. I believe we are quite close to needing a little bump in bandwidth. I am not (yet) out of the 15 SP range and I really noticed bandwidth problems on the weekends. To the point where I wrote one post, made one vote and then couldn't even redeem my rewards to up my SP. Not saying it's super terrible and impossible to work around but it can be discouraging for new users. I think eventually we have to ask "Do we only want the super engaged and hardcore people on Steemit? Or do we want more casual people as well?"

It is a balance act though, because increasing the bandwidth too much would make spamming worse and I don't think anybody wants that.
