I found this an interesting read about twitter. A peek into its numbers - it has 100M registered users. However, per RJMetrics research :
- 40% of its users have never tweeted
- 80% of its users have sent less than 10 tweets
- 1/4 of the accounts have no followers
- Average twitter user had 27 followers
Well, its the old Pareto principle or law of the vital few (80/20).
Twitter seems to be more like a feature-add on vs. a destination. Its something which is "syndicated" vs. being site where users will spend time on. Unlike facebook, Twitter's monetization potential is not in its site but in figuring out new revenue model based on the syndicated feeds. Had they focussed more on create a destination features such as new Twitter interface, sooner. They might have had a better chance. Instead they allowed myriad partner to create businesses filling in these holes (e.g. Twitpic, yfrog, etc).
