What is the difference between twitter accounts?

Question

What is the difference between http://twitter.com/#!/StackJudaism/ and http://twitter.com/#!/mi_yodeya?

Answer 1

@StackJudaism is a feed generated by StackExchange as a standard part of each SE site. It is fed automatically with "interesting questions every so often."

@mi_yodeya is an account I created back in the mi.yodeya days. I control it. The community uses it to tweet out timely Q&A on a daily basis. (More detail is here.)
