In 2010, I lived in the same place for all 12 months, the first time I’d done that since 2002. It was the first year since 1999 in which I spent no time in Boston. My rent tripled from 2009, but the median household income of my new neighborhood was 44% lower than my old one. I ate at the four Italian restaurants around my apartment 39 times. When I bought lunch on workdays, I spent an average of $6.94.

I ended the year subscribed to 806 RSS feeds and following 832 Twitter accounts. I sent 2,387 emails from my personal address in 2010, 39% of which were to the same three people. At work, I received 39,677 emails, or 109 a day. I performed 7,939 Google searches, and my third-most-frequent query was “em dash.” I tweeted 1,781 times.

On 125th Street, a basket of goods — two loose Parliaments, a Citarella fruit salad, tickets at the Apollo, and an egg sandwich — cost 24% more at the end of the year than at the beginning. A new Target opened over the summer at the eastern end of the street, but I haven’t been.

I went down the data rabbit hole in 2010, and one result was my blog post for the Journal, “Everything the Internet Knows About Me (Because I Asked It To).” Earlier, I analyzed a dataset of passwords chosen by Gawker Media users and revealed the contents of private Facebook messages misdirected to my inbox. My beat was secrets, I guess.

But most of my writing in 2010 was in the form of memos, comments, and random side projects. I left my review of The Social Network on Jeff Jarvis’ blog, and I acknowledged a mistake on Felix Salmon’s. My charitable contributions are in the comments of a Matt Cutts post.

I taught a course on social media at Columbia Journalism School. Throughout the year, I gave talks on social-media metrics at News Foo Camp, on social-media storytelling for the Online News Association, on geosocial news at the Community Managers Meetup, and on the economics of journalism at ASNE’s annual conference.

Lately, I’ve been playing around with the Google Books Ngram Viewer and created a Tumblr to collect top-notch ngrams. There’s a post still to be written on that. (Among other Tumblrs in 2010, some friends and I compiled a list of TV Shows That Are Sentences, and another season of Mad Men aired without my doing much with dickwhitman.com.)

I did not miss an episode of the following television shows in 2010: Friday Night Lights, Gossip Girl, Lost, Mad Men, Treme, which I blogged for the Journal, and True Blood. The Kids Are All Right was my favorite movie of the year. The best blog I discovered in 2010 was booktwo.org.

My favorite book was Freedom, which I read on Kindle for iPad and recently lent over Twitter. Which reminds me, I created an RSS feed that surfaces passages that are popularly highlighted by Kindle users.

The personal highlight of my year was the wedding of my friends Sarah and Simon. At the very end of 2010, I bought a 13″ MacBook Air.
