Twitter Glitch?

After my fine dining experience post fed to Twitter I had about 10 followers show up on Qwitter. I'm wondering if maybe there is a glitch in the system. I've had this happen before but I didn't really pay attention. This time these followers all stopped at the exact same time. What are the odds of that? Those that quit me are marketers and SEO gurus and folks that are going to tell me how to make money online fast! Twitter is great but there are also a lot of cons to it too. What do you think, glitch in the Twitter system?
