Yes, and that is my objection, aside form the annoyance factor. It's misleading at best, but really just plain lying.
I do think that the forum owners, in their efforts to increase traffic here are not taking into consideration that, while there aren't a lot of new threads, many of us have gotten into the habit of just posting in those long running type threads.
Back in the day people started a separate thread for every thing they had to say. Now we've got numerous varieties of random chat, random cat chat, random dog chat, morning threads, complaining threads, etc.
I think we've gravitated to those because specific topic threads don't seem to generate much interest any more, though I much preferred them.
