I think I prefer things as-is. We pretty much all tend to find the same users problematic, and they don't tend to stick around - either they leave or they're chucked out. I think it's better if we're all seeing the same site.

Such user-specific effects might be better done externally, as with greasemonkey.

For very simple things, you could use yahoo pipes. Here is a filter that removes lojban, from the feed of new comments. rss

It would be nice if the feed were more structured. I had to match the title, rather than the author of the comment.

Seconded.
