Tweeple aren’t happy with Twitter. The latest downtime, mid-afternoon (Eastern time in the US) the service went down yet again. This morning the sentiment is “so-so” according to Summize, which measures realtime sentiment on Twitter. Cnet’s Dave Rosenburg was quick to respond with disappointment in Twitter. His prognosis is not good. Rosenburg likens Twitter’s problems to “a sad Friendster-like uptime death spiral.”
