After reading, mashable earlier on twitter recent growth spike, I've just been playing with compete.com and found some interesting trends to share. 1 -Twitter's velocity is reletively high both historically and compared to its social rivals. 2 - Website Traffic is rising but is way short of fb and ms 3 - Twitter has risen up the long tail  4 - Google trend shows there is a long way to go NB API use not included. I've been wondering when twitter will tip in terms of user numbers.   How long will it take to reach 100m registrants? My prediction is by November 2010.  I'm now activily looking at twitter business opportunities and have some ideas. I think this is going to be an exciting space over the next couple of  years.
