I kinda miss the old board. And kinda not. I'm on the proverbial fence.
I am not resistant to change, but I did like the old format better. Without ad block this would be a nightmare.
Some of the features are better with this format....I think some of the features with the other format were better under the old system.
Bottom line: I think to call this an "upgrade" is a stretch. My guess all along is the change was done to either save money, or generate more money for the owners. The users of USMB who ultimately pay all the bills either as supporting members or by their presence (eyeballs on the screen) were a secondary consideration at best.
