With the plethora of tall sigs we've seen recently it's a LOT right now (inconsiderate bastards). Plus I've been adding people for more mundane sh**t again. It really speeds up the time I spend here. I'd guess in the low 20s.
That's gotta make threads hard to follow. Do the posts just disappear? Or does it give the name of the poster but then you just don't see the post? Can you disable the ignore feature once enabled? Like, ignore poster generally but for this post make it visible. I assume you can. But with 20 you probably find yourself un-ignoring as much as you ignore. What a hassle. My impression is that you're smart enough to ignore posts without the aid of software.
I agree with you about the profusion of busy signatures. I find signatures annoying, generally. But that's an easy fix. Have the signature script only allow 200 or so characters, and no images. That sort of thing. If it was something that the webmaster wanted to do I imagine he would. Simple enough. There's one poster who's always putting little movies of a cat doing mundane stuff. It's so mesmerizing. And annoying. I find myself staring at those for ten minutes before remembering to read the post.
