Seeking for original research tools I found MoodViews’ Moodgrapher: The Moodgrapher plots the mood levels reported by LiveJournal users in their posts. You can choose dates and pick desirable moods to search on. Moodgrapher will allow you to compare two different moods and will present it all in nice charts.
This concept much resembles wefeelfine (which collects emotions from a much larger database of blogs), but seems more friendly to research with.
Both applications are certainly part of a major research trend: using the blogsphere (do you know that “blogsphere” was found to be one of the most irritating words?) as a unique mirror to our mind.
See how much calmer and less busy we became towards NewYear (graph 1).
See love feelings generated on Valentine (graph 2).
See how Hurricane Katrina effected us before and during August 29, 2005 (graph 3)
Finally: the hottest moods in the blogsphere according to the last 10 minutes are:
The least popular moods are
graph 1 - busy vs. calm (NewYear) reports on posts
graph 2- loved vs lonely (Valentine). reports on blog posts
graph 3 – worried during Hurricane Katrina. reports on blog posts
