After writing 44 Social Media Insider columns this year, this 320th contribution to MediaPost offers a good time to reflect on what happened in 2010. Several themes emerged, with mobile social media standing out among all the rest. Here's the year in review.

As we head into the Christmas holiday, it's time for wish lists. Here's a theme-based one for people in social media: If Santa were to give you the gift of a perfect social network, what features would it contain? (And, yes, Virginia, this exercise assumes that Facebook -- for all of its world dominance -- still isn't perfect.)

For nine days, I was silent. The world heard not a tweet, not a Facebook post, not an email from me. This is the story of one man who went to four South American countries with nothing but an iPhone, two digital cameras, a Kindle, and a couple suitcases, and survived without social media in even the darkest of times, like when I really could have used restaurant recommendations.

And the winner is Mark Zuckerberg, in a walk!

No one ever reads, or comments on, my columns to do with Myspace. But, since hope springs eternal, let me try again. Here's a thought: What if Google bought Myspace?See? Throw Google into the sentence and everything starts to change! I put Google in the mix not just because it's a craven ploy to get you to read this column, but because the idea of it's buying Myspace was actually floated by Gawker, after News Corp. COO Chase Carey 'fessed up at the Reuters Global Media Summit that Myspace was on the block.
