Thank you so much for this! Miss Snark linked you again but this is the first time around for me so I'm very glad for it.

Question: what is the etiquette regarding handing out business cards? If I've bumped into you in the coffee line and we had a pleasant 2 minute conversation, should I offer my card? Or would I come across as a used car salesman? I'm assuming I shouldn't be handing over my card as you discard your paper towel in the bathroom, but are there general guidelines about when is appropriate and when is pushy?

Thank you!
