Sarah Palin is communicating through social networking sites after her surprise announcement last week that she will resign as Alaska governor.

Throughout the holiday weekend, the governor has provided frequent updates to supporters on Twitter while otherwise laying low.

She also turned to Facebook, citing a "higher calling" to unite the nation along conservative lines.

Palin spokeswoman Sharon Leighow said Monday the governor often Tweets on weekends and "this past weekend was no different."

Political analyst Larry Sabato says online networking is a perfect vehicle for "a controversial politician to communicate
with her public in an unfiltered way."

Palin's attorney Thomas Van Flein says Palin has kept in touch with several people, including him.
