The letter area for this blog has become very active.
The signal to noise ratio decreases as a result.
An example of a greasemonkey script that creates a filter list can be found associated with Pharyngula. Note that each individual handles their own filter, i.e., it only affects what the user sees, not what is posted. The Pharyngula version shows the post as "dumb comment removed" so you know it was there and can remove the commenter from the list at every post.
Would one of you clever programmers PLEASE create one for these comments?
I personally am very reluctant to filter someone and very quick to remove them at any opportunity, but I would hate for this blog to become a food fight like TP.
