@ossobuco,
Back re my old land use threads..
This is not a whine -
They were in part a kind of chronicle for myself at the same time they were a call to others to comment, not unlike what Robert is doing with his collection threads, just different subject matter (though not always, really) and less told by video. They were the result of some fair time of reviewing land use commentary sites, so that some hours went into each little answered thread.
I did get it, that either I didn't make threads interesting enough, or the interest wasn't there in that 24 hour period, or (fill in your own blank). But when the threads did pick up attention, they caught some spark.. Walter did a lot of these types of threads too, as did a few others, noinipo (sp?), for example.
At some point, those may all be tagged, useful for some few of us, or perhaps to others in googleworld.
I think the potential for interest clusters is fantastic here. I sure wish people wouldn't leave out of boredom or frustration.
