From what I have seen, I see other issues factoring in to the large number of Twitter Quitters. First and maybe foremost, if you do have an issue, Twitter simply does not provide support. There biggest support feature is a forum. However, support from Twitter is essentially non-existent. Twitter users may complain of the same issues for months and those complaints are virtually ignored, or in some instances, they simply say the issue has been resolved. From a customer service standpoint, you simply cannot ignore customer issues and expect them to go away. Let me clarify that.. you cannot expect the issues to go away. You can expect the customers to go away. Another negative is that Twitter appears to be a breeding ground for MLM programs with some incredible claims; of which, some cannot be supported, or are clearly false, or will get your account deleted by using some of their tools. Without regulating the dissemination of this type of content, what happens is that Twitter users are inundated with hundreds of repetitive MLM-hype tweets. I imagine that some people simply get tired of it. I have also seen complaints about receiving unwanted porn. There is a process to unfollow someone. You can select to block another user. However, processes do not always work; and sometimes basic functions do not work for random users. There appears to be no fix for these issues. When these processes and functions do not work properly, Twitter fails miserably on addressing these type of customer complaints. Allowing itself to be exploited and failing to handle customer issues will only continue to contribute to high Twitter Quitter rates; consistent with your projections about the unlikelihood of Twitter’s long term sustainability.

I believe that if MySpace were to add a similar method of mobile messaging they would recover from their 31 point dive and blow Twitter out of the water.

I mean, when I first signed up with Twitter, I found it to be useful and have only stuck around because I enjoy the people I’ve followed that I would otherwise not have found. However, the constant drops of service, outages, etc. are extremely annoying.

Even going through the recent tweets and then checking the first tweet date does not necessarily work – because it is possible that some users (especially recent joiners who are simply following celebrities) might be just reading and never writing.

However, I would expect a high attrition rate amoung the people who signed up simply because they heard or saw a popular celebrity mention it on radio or TV.
