State of the Twittershpere by HubSpot

Hubspot released their Q4 report, "State of the Twittersphere". Hubspot first released this report in Q1 of 2008 so any comparative analysis will have to wait until Q1 2009. Some interesting data to note:

• 4-5 million users
• 70% of Twitter users joined in 2008
• 20% of Twitter users joined in the past 60 days
• 5-10K new accounts are created everyday
• 30% of Twitter users are relatively new or unengaged - do not post more then once a week and follow few people
• Traffic has grown by 600% over the last 12 months

The report also looked at what days were the most active to Tweet. They found that there is about 50% more activity on the weekday versus the weekend. People tend to tweet most often on Wednesday and Thursday. So it may be best to release a product or promote a blog during these two days.
