None-- I think it’s petty.
I’ve never really “gotten” ignore lists. My options are to skip OPs written by anyone who tends to bug me (as twickster said), or to simply not get my knickers in a twist about anyone who tends to bug me. It’s just a message board. I think that if you’ve let anyone get to you enough that you’d put them on an ignore list, it might be best to take a break from the board as a whole. 
Same here.
Ditto. I tried it with one poster a while ago, and it drove me batty that you could still see that they posted, but not the contents of the post. So I took them off ignore and just ignored their posts the old-fashioned way.
I realized that I typically don’t pay that much attention to usernames anyways while I’m reading a thread - I only look at the name maybe half the time or less - if I’m replying to them or trying to follow a conversation.
Everybody.
I’ve placed every single poster on my ignore list. It takes a lot of time and continued maintenance, but it’s not like you can afford to skimp on the important stuff.
In unrelated news, I can’t help but notice that everyone on the SDMB seems to agree with me in all particulars, since no one ever posts a contrary opinion.
(OK, I admit I didn’t know we had ignore lists, either.)
None. I also ignore people the old-fashioned way.
Wow, who would’ve thought that there was ignore snobbery? Definitely getting a vibe from some of the posts here that there’s something inferior about using the feature, which I’m really not understanding. If I’m not interested in seeing what they have to say, why not take advantage of the technology?
If most dopers use the “old-fashioned way”, then I am on most of their “old-fashioned” ignore lists

Us luddites just don’t consider someone ignored if there’s no lorgnette to peer through.
No one. Quite frankly, I find it to be silly.
I’ve thought about it. I felt someone was seeking me out to argue with every little thing I posted. But I decided that was a very childish thing to do and the whole reason you’re on a message board is to read what others have to say.
It kinda diminishes the “fighting ignorance” aspect of why we’re here. Besides, people will be jerks no matter what you do.
Did you say something? 
“Ignore snobbery”, eh? Well, perhaps. I also find it silly; maybe that’s just because I haven’t felt the need to use it yet.
Dude, I think you might be taking the thread too seriously (or too personally, or something): I don’t understand why anyone would put someone else on an ignore list, and I think that feeling the need to do so might indicate an underlying issue, but I’m only expressing this opinion because the OP brought it up. I don’t really give a rat’s ass whether anyone uses the feature.
…aaaand, I realize that you might not even see this reply.
I get what you’re saying, but i don’t think it’s snobbery. Or at least, not in my case.
There are people whose OPs i will generally ignore, and others whose posts i will often skim without reading closely. But for the most part, if i’m participating actively in a thread, i want to read everyone’s posts.
Not only that, but as far as i know the “ignore” function is a blanket one—it cannot be applied to only one forum. There are people who annoy the fuck out of me in GD or The Pit, but whom i find affable and interesting in Cafe Society, and informative in GQ. I don’t want to miss out on their useful contributions just because they are assholes in one particular forum.
But that makes no sense! If you’re peering at them through your lorgnette you’re paying more attention to them, not less.
Oh gee, I just opened myself up to another accusation of taking this thread too seriously, didn’t I.
Judging by the responses I get to my posts I think that there about 12 Dopers who don’t have me on their ignore list.
Zero. To do so would mean (a) I’d have to start figuring how to tell most people apart around here, and (b) I’d have to figure out how to work/enter/operate/engage/find my Ignore List in the first place.
Used to have one but that was back around election time. With it’s passing this person’s behavior has become more tolerable. So now… zero.
I don’t have anyone on the list. If I want to ignore someone’s post, I just skip over it. If I’m on someone’s list, big deal. I’m almost positive I’ll get over it.
I don’t need an ignore list, and I’m on everyone else’s by default. See? You probably had to override your list just to read this.
Next week, I’ll post the entire meaning of life.
