As always, Ethan Zuckerman brings together all the threads surrounding the Guatemala protests, including information about the arrested Twitter user and some "trending topics" muckraking:

I ran a little tool I developed a few weeks back to check the frequency with which phrases and hashtags appear on Twitter. #escandalogt isn’t hugely frequent, registering at 0.052% - compared to #swineflu, for instance, which was running at over 2% at the height of hype/hysteria. What’s interesting is that #escandalogt is about as frequent as several of the tags listed on Twitter’s “Trending Topics”, getting more use than #fixreplies, #GoogleFail and #theoffice, all currently featured on the right sidebar. It’ll be interesting to see whether #escandalogt emerges there… or whether this is a sign that those topics aren’t entirely algorithmically generated and some human curation is involved.
