Although I don’t count Twitter as an Instant Messaging service, it’s interesting to see this statistic published by Palo Alto Network few days ago.

In the report, they put Twitter together with other popular IMer like msn, facebook chat, google chat and meebo. Surprisingly, they all went up since Spring this year, and even more surprising is that Twitter beats others as an “Instant Messaging” application. Guys, did we tweet THAT much!?

Feel free to leave me a message for full report.
