I admit I'm on Fb more these days. I like keeping in touch with old friends and far flung relatives, as well as those closer to home. I don't tend to have work colleagues on there. In particular, I am happier posting personal photos and info to a selected group rather than to the general public. I also found Fb was a useful additional site for advertising PONGS events.
I got embarrassed logging on to TP and seeing my name appear consistently as the last poster. If I felt like that, I can imagine what others thought! I think you need a crucial core of regular posters and that number has dropped. As you say, there will be a variety of reasons for that - for example,some have moved out of the area and others have new ventures off line - but the end result is the same. Unless new folk take the place of those who have dropped out, then things will grind to a halt.
The Matters thread still seems to have bursts of activity, but G&TT is certainly much quieter. As Epykat says, the fun element has dwindled.
I'm already breaking out in a cold sweat wondering how long my name will appear as the last poster.
