The Pew Internet and American Life Project published a report recently that details the increasing acceptance/popularity of the status update. Irked or not, the status update (or similar feature) is strengthening its foothold. Oh meta remediated lifetstyle how I love thee.
The report, Twitter and Status Updating, Fall 2009, is linked here.
Lastly, and of note, the report states that 19% of internet users claim to use Twitter or another service to share updates about themselves, or to view updates about others. When Pew surveyed the same group in April 2009 and in December 2008, 11% of internet users claimed to use a status-update service.
