Holiday cards - what's your opinion?

The concept of mailing something out to a hundred or so friends is quite appealing - and yet the decades roll by without my doing it.

I'm thinking this year it's time. While there's no big news, that in itself is news, and I don't want to drop into my Mom's habit of only contacting people during/after deaths and disasters.

My first roadblock: I don't have near as many postal addresses as I though I had.

Do you mail something out this time of year?
