I was going to mention something about these new tags that are visible all over the forum but that would be unproductive, so let me just say - keep changing things so that when we're just about used to one thing, there's a new thing. It probably stimulates learning, or crankiness, or both.
Is there an official forum design feedback thread?
I think the newly (re)introduced labels are helpful but having them right under the topic title in the listing impedes glancing over the topics to quickly check for the ones that interest me. Too much visual information to process. I'd prefer the labels to be in their own column. That 'd improve the readability of the topics listing.
