I noticed tonight on my laptop that the real estate consumed by the delayed screen refresh was more tonight that previous nights. I use the dreaded ad blocking software whose name is anathema to Internet Brands. When I display "New Threads, I would have full screen used, then, an inch or so would be reclaimed on the right, though nothing was displayed there. Tonight it is 1.5-2 in.
I also see something similar to the above display on my iPad. I am pessimistic enough to believe that this reclamation of screen real estate is the slow, inexorable move to forcing ads on us.
