Ben, for most these threads are likely just a way to pass a free moment or two when there's not enough time to actually go out and do real photography. I work from home. Software development. I keep APUG on a side monitor. When I get a free moment between debugging product build cycles I occasionally jump in with a drive-by post.
Like right now.
This weekend I'll be out with the 8x10, weather permitting. But I can't fit that in during the wait for a three-minute debugging build on a Friday afternoon while working.
These weekday afternoon threads are like all the Old Farts sitting around the porch at the General Store on a Saturday afternoon simply BSing to pass the time.
