too much information
Thus far the filter contains two type of people--those whom I love, and those who have given me the impression of being understanding and unlikely to twitch if I happen to share something that really does fall under the category of "too much information".
If you are on the filter, you can see the test message (from 31 March of 2009) asking anyone who doesn't wish to be on it to please let me know. If you can't see that message, but would wish to, please let me know. I have enough "friends" on LJ it is possible I missed a few folk who belong on that list when creating it.
