About once a week, so see if someone has requested my presence in a thread I’m not reading. Which happens way less than once a week. 
The first thing I do is search my name to see if there are any responses to anything I posted.
Fairly often, but I’m rarely mentioned.
I don’t remember, but this thread inspired me to do one, and it revealed two instances where Skald said that he covets my username. I better watch out.
I concur.
Also, when I chose my name, I did not properly plan ahead for the possibility that I might someday actually want to run vanity searches. Now, it’s all but impossible to wade through the morass to see if any of the references are actually to me. (If we ever get case-sensitive search, that’d probably easy things). Still, I try, from time to time, and on those rare occasions when I am invoked, I am stoked.
Fairly recently, only it wasn’t a vanity search so much as I just went back and looked at my old posts.
I feel out of place here (I know, woe is me, right? but it’s my fault, not a complaint against anyone else.) since I’ve been back and I thought looking at the stuff I used to talk about would make me feel like I had more to say. Instead it mostly made me realize I didn’t even recognize who I was two years ago. And even though I was really obnoxious back then, I think I liked that version of myself better than this one.
A week ago. I was curious if people wondered where those of us probably bothered by the icestorm disappeared to for several days. Nope.
I’ve never done a vanity search.
I’ll do a search of threads I’ve posted in every time I log on. I thought this was standard procedure. How the heck are you supposed know if someone has responded to something you said? What if they have a question about something you said?
Or do some people just not care? 
That said, I’m still pretty vain, so I’m pretty sure I’d do it on a regular basis regardless.
You can subscribe to those threads (indeed, you can set it up so you are automatically subscribed to any thread you post in). Then you need not cast any manual searches for your name.
I did just a few days ago, but I don’t very often (i.e. once or twice a year.)
The last upgrade seems to have removed the ability to do quoted searches, so where I used to be able to search for “sage rat” I now have to search for sage, since rat is only three letters and is ignored. It brought up a lot of cooking threads and threads about some rapper named Sage Francis or something.
Not ideal.
OT, but I’ve noticed that about half of people who write Sage Rat will forego the space. Not sure why they do that.
So you did wander off. I wondered about you and I have to say, the thought of you being obnoxious never crossed my mind. On my mental list of dopers I can name, you are one of them.
Let’s see, posters in this thread alone include:
Auntbeast
SurrenderDorothy
ParentalAdvisory
Did I miss anybody? 
I just did a few days ago, but that was just to check if I was mentioned in the “Posters You Can’t Stand” thread.
I wasn’t.
Never. I already know what the result would be.
Pig is a three-letter word, and searching on Freddy gives hits for eddyteddyfreddy, who posts and gets mentioned more often. So no, I don’t bother.
Never. But I do admit to doing vanity searches in Mafia spoiler boards, since that’s the only place I might conceivably be mentioned.
You might be surprised. Sometimes I’ll do one here and only select the Game Room. Try it. You’ll have tons of hits.
I’ll be damned, Idle, you were right. Granted, a very large number of hits were mafia-related, but I also learned that my name was invoked in the Never Have I Ever thread, presumably so they could all take poor buff’s toothpicks away. 
I also got a case of the warm snugglies from one post, so may I just remind you, Idle: you are a genius!
I never even considered it… I’ve been here 10 years and have like 270 posts (I read pretty much every day, though!). Most from when I was like 16, so I really don’t want to dredge those up. I doubt anyone would have much reason to mention me. It would be awesome, though, I must admit!
