Hello, I've noticed that there is no easy way to delete multiple comments at once. This is a critical feature, since between spammers and trolls, one is often faced with a need to delete several comments in a single shot without having to reassure the server of one's seriousness. The obvious way to do this would be to put checkboxes next to every comment and have a mass action button, more or less the same way they do at LiveJournal.
It's a pain right now just to delete one comment with the default drupal install. Having to go to seperate confirmation page just to delete one (!) comment is way too much.
Also, while I'm here, I've noticed that drupal does not generate particularly useful user pages by default. The userposts module provides a listing of nodes and pages created by the user, but not comments. Even at that, it's a little primitive. User pages with comment listings are critical to fostering a sense of identity on community oriented blogs. Without a record of what people have written in the past, most users become little more than names attached to comments. History is important in establishing continuity of personality. I would say that Scoop is the gold standard as far as user pages go, so it'd probably be good to try to emulate their setup.
I managed to hack the userpage module up a bit to put some recent comments on the page in addition to the usual nodes, book entries, and so on (even seperated it into nice little columns), but it's quite primitive.
