Seems like the ads are gone? Down for retooling maybe? Regardless of why, good riddance!
I know MR needs revenue. As mentioned in another post, ads that appear in between posts, with different formatting are an option. Ads that look like a member talking in a discussion are disconcerting. The uncanny silicone valley...
Possibly on this topic, I've noticed the forum acting rather buggy since the appearance of the ads, or perhaps since their removal.
Some threads have a phantom last page. You click on page 6, but it's really just page 5. I've seen this temporarily here and there before, but I feel like there's been several occurances lately.
Also, the "last post by" seems to be lagging. If I make a reply to a thread, the index of the forum typically says my name under the topic immediately. Several times over the past day or so, it says the previous poster's name, not the current one.
