Though I don't agree with you, Digital, I get the feeling there is a little more to the change of heart about chain threads, as opposed to your contributions to them just a few weeks ago, than just feeling that they have run their course.
That's just a feeling though and I apologize up front if I am plainly wrong.
The chain threads may seem pointless, but they serve several purposes, not the least of which is simple social interaction which is pretty much free from contrasting opinions, abrasions, and bruised feelings, of which the present thread is not.
I came to meet you, Badmash, Marry, and others who were taking part in these threads after an absence from the board of several months. These threads are completely casual, and yes pointless, but provide a way for others to rub elbows and get acquainted in an atmosphere where conflicts are likely not to happen. I'm just not seeing that as a bad thing and I think that threads which bring people together, even for the most trivial of reasons, cannot be classified as something bad.
Just my opinion though.
