British singer Estelle attended the launch party for Belvedere Pop-Up Shop over in London yesterday. Estelle has been traveling back and forth between the U.S. and London for the past several days. We know this because she told us so yesterday on her Twitter page. We also know exactly what time the wheels on her jet lifted up off the ground because she told us that too. In fact, it seems there is hardly anything that Twitter addicts won’t reveal about themselves on the social networking site.

You can find Estelle, and her fellow Twitter addict Solange Knowles, Twittering away at all hours of the day and night yapping about what they ate, drank or whether it’s raining outside their window. There is a fine line between addictive personalities like Estelle and Solange — and narcissists who think their lives are so important that they have to fill us in on every microscopic detail of it.

The endless tweets of Twitter addicts contain zero calories and are, in fact very boring to the rest of us who are mining Twitter Land for actual information that we can use.

What Twitter addicts fail to realize is that the quality of their twits is more important as a whole than what they are doing every minute of their lives. Wouldn’t it be a sad world if all we did all day was sit and wait for an update from someone on Twitter who thinks the world revolves around them?
