Twitterizer started in May of 2008 as an excuse for me to explore design patterns, have a little fun coding, and stretch out my architectural legs. I never set out to create an open source library, much less a popular one (in the last 30 days of its life, Twitterizer.net pulled 8,560 unique visitors and nearly 52k views).
After 4 years of maintenance, a complete rewrite, two addon projects, lots of mistakes (some never fixed), and thousands of questions answered, I grew tired. I had always intended to take a break and pull myself back into it, but the longer time has gone on, the harder it has been to even consider dedicating the time required to get the project to a useful state again (hint: the library was never 'feature complete').
In the end, I got far more out of this project than I ever hoped. I've worked along side absolutely amazing people and gained some insight into a few breathtaking projects. If not for those people and those projects, I doubt I would have lasted as long as I had.

In 2009 the Smuxi project made use of the Twitterizer library to support Twitter as a built-in feature in their popular IRC client. As of 2013 Twitterizer is part of the Smuxi project umbrella and thus actively maintained. In August 2012 Smuxi ported Twitterizer to Newtonson.Json 4.5.8, in August 2013 Twitterizer was ported to the Twitter v1.1 API, in November 2013 proxy support was added to the Streaming API, and in Janary 2014 Twitterizer was ported to enforced HTTPS.
