Twitter! You can use it at concerts. And many rock critics do. Herewith, an initial survey of some of the funniest short observations from Washington-area shows this past year. Want to nominate something for the next parts of this series (and spare me the task of reading an entire year of one person's tweets, which I assure you IS NOT A LOT OF FUN, TECH-WISE)? E-mail me!

TWEET CASE STUDY: CHRIS KLIMEK

Klimek writes for the Washington Post, Washington City Paper, and DCist, so he gets plenty of practice killing it at live gigs. Choosing three tweets from this prolific funny person was this writer's greatest Dec. 27-based challenge so far.

TWEET CASE STUDY: DAVID MALITZ

The Washington Post pop critic attends more concerts than seems humanly possible (when contacted for this piece, Malitz, who was enjoying the holidays, apologized for not having his spreadsheet of concerts he attended in 2011 available on his non-work computer).

On attending a Fucked Up performance:

 On attending a Taylor Momsen show at Jammin' Java:

TWEET CASE STUDY: JONATHAN L. FISCHER

Washington City Paper's arts editor is also a frequent presence at rock concerts in the Washington area. Like Malitz, he did some of his best work at the Smashing Pumpkins reunion show at the 9:30 Club this fall, but his relentless attendance of summer festivals also yielded some gems.
