Recently my karma changed from negative to neutral, and then to positive.
A long time ago, someone had caused my karma to go negative. Since then, my comments have probably been largely invisible. But a kind soul gave me a boost recently. And then I managed to post something interesting enough to move into positive territory.
It's been a long time, but I'm grateful.
Not that I post very much, but it's been a bit depressing at some low level for a couple of years.
