@WeFeelFine: will sentiment lift with the news of a Royal Wedding?

Harvesting the data we submit to the social web and using it to make a judgement about how “we” feel. 

We Feel Fine has been harvesting human feelings from a large number of weblogs and every few minutes, the system searches the world's newly posted blog entries for occurrences of the phrases "I feel" and "I am feeling". When it finds such a phrase, it records the full sentence, up to the period, and identifies the "feeling" expressed in that sentence (e.g. sad, happy, depressed, etc.). Because blogs are structured in largely standard ways, the age, gender, and geographical location of the author can often be extracted and saved along with the sentence, as can the local weather conditions at the time the sentence was written. All of this information is saved.

I wonder how it changes with the announcement of a Royal Engagement?
