A minor tweak may turn your head on Twitter and other sites. Google announced it will use g.co as a link shortener for official products and services, following the lead of Twitter (t.co) and o.co, formerly known as Overstock.com, on the path to true brevity.
The .co domain name is the top-level domain of Colombia, much like bit.ly’s post-dot text identifies it with Libya — something that’s caused some concern in the past.
The people who run the .Co Domain Registration, headed by CEO Juan Diego Calle, have said that there should be no reliability concerns about the domain name, however, because the group worked with the Colombian government on its global launch in July 2010. As of last month, the group had registered 1 million domain names.
Google said it will still use goog.gl — .gl is the top-level domain name for Greenland — to shorten some URLs and for public use.
