That is what I noticed too. I kinda stopped going there because no one was on. And, in my case, no one seemed to respond to my threads.
The people on here always respond and are very nice. I like how the forum is setup too. :)
By far. PawTalk was my first but nobody's around now. Except spammers looking for simple google-able questions. I check it everyday through habit but my CP is always either empty or has some dead threads in it. Boring. :)
