This.
My friends and I joke the site should be called "BGA-Just press F5" because of how often things go wrong.
I've been fine with it because until now I've considered the service underpriced, so the white-glue-and-scotch-tape UI was acceptable, even part of the character of the place.
So I'm disappointed to hear that one of the justifications for the price increase is that you think you've already improved parts of the UI. If this price increase were to help afford more/better engineers to fix the many glitches and bugs, that would have some appeal, but it seems you think you've already done that work, so I have no reason to believe the UI is ever going to get good enough to justify the higher price.
