Facebook has a feature called Lexicon and it can be used for several interesting purposes. Facebook explains:
Lexicon is a tool to follow language trends across Facebook. Specifically, Lexicon looks at the usage of words and phrases on profile, group and event Walls. For example, you can enter “love, hate” (without quotations) to compare the usage of these two words on Facebook Walls. You may enter up to five terms, where each term can be a word or two-word phrase consisting of letters and numbers.
One of their examples is party tonight and hangover. As the graph below shows, party tonight peaks on Friday and Saturday and hangover lags closely behind, peaking on Saturday and Sunday.

I did a search on Obama, Barack, Clinton, Hillary. (Click on the picture below for a bigger graph.) I also point out a few important primaries/caucuses in the graph. And I admit willingly that I do not have a black belt in calligraphy.
A few results:
- Barack Obama is discussed more than Hillary Clinton.
- Big jump for Obama after his surprising win in Iowa.
- People refer to Barack Obama as Obama and Hillary Clinton as Hillary. Perhaps because there are many Clintons, perhaps because she is a woman. I do not know.

That Obama is a more popular discussion topic than Hillary Clinton is perhaps not surprising since the average Facebook user is young and often well-educated.
But note also that publicity is not always good. The graph below is for Knicks, Celtics, the two basketball teams from New York and Boston, respectively. Knicks played poorly this year, as they have done many years now. Celtics, on the other hand, improved their game dramatically compared to last season. The jump during the spring for Celtics reflects the beginning of the playoffs.
The spike for Knicks reflects a spectacular loss against the Celtics in November 29, 2007. They lost by about 10,000 points and it was shown on prime time television.
So just because people talk about you does not mean they praise you. However, I think it is a safe bet that the spikes for Obama reflect mostly positive comments as polls repeatedly show his popularity among young people.
