Sending Christmas greetings to networking contacts?

I wouldn't do that. Too corny

No. No, no, no, no, no. Especially if they're analysts/associates.

They'll already be on edge around the holidays and will have a mini heart attack every time their blackberries buzz.

Follow up to OPs question:

Always trying to stay in the radar of the people I networked with when I was in college, is that more acceptable? Just to stay friendly. Im a 1st year at a BB

If I got Christmas/Happy holidays cards from the various eager wannabees I've met, I'd see it as a sign of keening, over-eager desperation and I'd throw the card in the bid immediately to disassociate myself from the shame that they've made me an unwilling party to.

Wishing you all advance Merry Christmas and a Prosperous New Year. At this time, we’re looking forward to seeing what the next year brings! On the occurrence of Christmas, we have a tremendous collection of Christmas Greeting Words. On this special Day we want to meet people and wish them Merry Christmas but sometimes it is not possible to wish by meeting them due to distance or any other reason. So, don't worry you can send special Merry Christmas via SMS wishes to them and make them feel pleased by wishing them or you can make your own Christmas Text Messages and Wishes forward it to them.

What if they celebrate Hanukkkah? You're screwed!
