Twitter had been on fire since the end of 2008 with eye-popping growth numbers. Mass Media were quick to pick up on the trend with players like CNN and ESPN developing several profiles and promoting the microblogging site on-air. The social-networking site seemed to be destined for greatness.

That may have just changed, Compete’s most recent numbers show that Twitter’s growth leveled off last month. The social site grew a mere 1% in uniques from April-May. The site may be losing some of its hype.

Also, an article by VentureBeat sites a Hubspot study that shows 53% of Twitter users don’t have any followers and 76% have failed to complete a bio. Granted, some of these profiles are spammers, others may have signed up just to follow Oprah in April. Whatever the reason, growth slowed earlier than expected and plenty have thrown up red flags this week that Twitter may be losing its luster.

It’s too early to judge whether Twitter will have the staying power of Facebook or not. It seems that their has been testing into Flickr integration through email uploads which could increase usability.

One thing is certain, Twitter has made major search engines aware of the need for real-time search.
